From this literature《Gold-catalysed asymmetric net addition of unactivated propargylic C-H bonds to tethered aldehydes》,we know some information about this compound(17739-45-6)Computed Properties of C7H13BrO2, but this is not all information, there are many literatures related to this compound(17739-45-6).

Computed Properties of C7H13BrO2. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 2-(2-Bromoethoxy)tetrahydro-2H-pyran, is researched, Molecular C7H13BrO2, CAS is 17739-45-6, about Gold-catalysed asymmetric net addition of unactivated propargylic C-H bonds to tethered aldehydes. Author is Li, Ting; Cheng, Xinpeng; Qian, Pengcheng; Zhang, Liming.

The asym. one-step net addition of unactivated propargylic C-H bonds to aldehydes such as 7-(dimethyl(phenyl)silyl)hept-6-ynal, 4-(benzyloxy)-7-(tert-butyldimethylsilyl)hept-6-ynal, 7-(tert-Butyldimethylsilyl)-2-phenylhept-6-ynal, etc. leads to an atom-economic construction of versatile chiral homopropargylic alcs. e.g., I, but has not yet been realized. Here, implementation in an intramol. manner under mild reaction conditions have been showed. This chem.-via cooperative gold catalysis enabled by chiral bifunctional phosphine ligands (1R/1S)-II (R = Me, Cy; R1 = H, Me)-achieves asym. catalytic deprotonation of propargylic C-H (pKa > 30) by a tertiary amine group (pKa ≈ 10) of the ligand in the presence of much more acidic aldehydic α-hydrogens (pKa ≈ 17). The reaction exhibits a broad scope and readily accommodates various functional groups. The cyclopentane/cyclohexane-fused homopropargylic alc. products e.g., III are formed with excellent enantiomeric excesses and high trans-selectivities with or without a preexisting substrate chiral center. D. functional theory studies of the reaction support the conceived reaction mechanism and the calculated energetics corroborate the observed stereoselectivity and confirm addnl. metal-ligand cooperation.

Research on new synthetic routes about 17739-45-6

From this literature《New GSH-responsive amphiphilic zinc(II) phthalocyanine micelles as efficient drug carriers for combinatorial cancer therapy》,we know some information about this compound(17739-45-6)Synthetic Route of C7H13BrO2, but this is not all information, there are many literatures related to this compound(17739-45-6).

Synthetic Route of C7H13BrO2. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 2-(2-Bromoethoxy)tetrahydro-2H-pyran, is researched, Molecular C7H13BrO2, CAS is 17739-45-6, about New GSH-responsive amphiphilic zinc(II) phthalocyanine micelles as efficient drug carriers for combinatorial cancer therapy. Author is Guo, Shanlei; Gao, Bo; Li, Dongni.

Combination therapies for the treatment of cancer have attracted wide attention. The poor selectivity and biocompatibility of photosensitizers (PS) limit the use of combination therapies in chemotherapy and photodynamic therapy (PDT) for cancer. In this work, the Gender PS (mPEG-b-PLA-S-S-ZnPC), asym. zinc(II) phthalocyanine (ZnPC) and mono-methoxy oxygen-based polyethylene glycol-polylactic acid (mPEG-b-PLA) were designed and synthesized for PDT through disulfide bond (-S-S-). The amphipathic PS could be self-assembled into a micelle in aqueous solution, and paclitaxel (PTX) was encapsulated in the core of the micelle for chemotherapy (PTX/mPEG-b-PLA-S-S-ZnPc). The PTX/mPEG-b-PLA-S-S-ZnPc micelle was spherical with a uniform diameter of about 184 nm. At the first 48 h, the release behaviors of ZnPC and PTX at 10 mmol / L GSH were 30% and 75.2%, resp. These results suggested that GSH-responsive PTX/mPEG-b-PLA-S-S-ZnPc micelle was an active ingredient in combination therapies for cancer.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Description of the bacterial RNA polymerase inhibitor GE23077-producer Actinomadura sp. NRRL B-65521T as Actinomadura lepetitiana sp. nov, published in 2020, which mentions a compound: 17739-45-6, mainly applied to Actinomadura bacterial RNA polymerase inhibitor; Actinomadura lepetitiana sp. nov; Actinomadura sp. NRRL B-65521; actinomycetes; antibiotics; bacterial RNA polymerase inhibitor GE23077, Electric Literature of C7H13BrO2.

The filamentous actinomycete that produces the antibiotic GE23077 was isolated by the Lepetit Research Group from a soil sample collected in Thailand, and it was classified as a member of the genus Actinomadura on the basis of its morphol. and cell-wall composition Phylogenetic anal. based on 16S rRNA gene sequences indicated that this strain formed a distinct monophyletic line within the genus Actinomadura, and it was most closely related to Actinomadura bangladeshensis DSM 45347T (99.31% similarity) and Actinomadura mexicana DSM 44485T (98.94%). The GE23077-producing strain formed an extensively branched, non-fragmented vegetative mycelium; no pseudosporangia were formed and the arthrospores were organized in slightly twisted chains. The cell wall contained meso-2,6-diaminopimelic acid and the diagnostic sugar was madurose. The predominant menaquinone was MK-9(H6), with minor amounts of MK-9(H8) and MK-9(H4). The diagnostic phospholipids were phosphatidylinositol and diphosphatidylglycerol. The major cellular fatty acids were C16:0 and tuberculostearic acid (10-methyloctadecanoic acid), followed by minor amounts of C18:1ω9c, C16:1ω7c and 10-methylheptadecanoic acid. The genomic DNA G + C content was 71.77 mol%. Significant differences in the morphol., chemotaxonomic and biochem. data, and the low DNA-DNA relatedness between the GE23077-producing strain and closely related type strains clearly demonstrate that it represents a novel species of the genus Actinomadura, for which the name Actinomadura lepetitiana sp. nov. is proposed. The type strain is NRRL B-65521T(= LMG 31258T = DSM 109019T).

Extended knowledge of 17739-45-6

Here is just a brief introduction to this compound(17739-45-6)SDS of cas: 17739-45-6, more information about the compound(2-(2-Bromoethoxy)tetrahydro-2H-pyran) is in the article, you can click the link below.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Chitosan-based multi-liposomal complexes: Synthesis, biodegradability and cytotoxicity, published in 2021-04-30, which mentions a compound: 17739-45-6, mainly applied to chitosan liposomal complex biodegradability cytotoxicity; Biodegradation; Chitosan; Cytotoxicity; Liposome; Multi-liposomal container; Passive targeting mechanism, SDS of cas: 17739-45-6.

Anionic liposomes were electrostatically adsorbed onto the surface of cationic chitosan particles crosslinked by sulfate anions, forming multi-liposomal containers (MLCs) for encapsulation and delivery of bioactive substances. An increase in mol. mass of chitosan from 30 to 300 kDa results in a size increase of chitosan particles, from 200 to 400 nm. Being saturated by liposomes, chitosan particles give MLCs of 320-540 nm. Each chitosan particle carries between 60 and 200 liposomes. The proteolytic complex Morikrase, a mixture of enzymes with various specificities, induces degradation of MLCs down to particles of size 10-15 nm; the higher the mol. mass of chitosan, the slower the enzyme-induced MLCs′ degradation pH variation within 5.5-7 and cholesterol incorporation into the liposomal membrane both have a minor effect on the rate of MLCs′ biodegradation Both the MLCs and the products of their biodegradation show low cytotoxicity. These results are of interest for constructing biodegradable capacious carriers of bioactive substances.
