Geometry-Retentive C-Alkenylation of Lithiated alpha-Aminonitriles: Quaternary alpha-Alkenyl Amino Acids and Hydantoins

alpha-Amino nitriles tethered to alkenes through a urea linkage undergo intramolecular C-alkenylation on treatment with base by attack of the lithionitrile derivatives on the N?-alkenyl group. A geometry-retentive alkene shift affords stereospecifically the E or Z isomer of the 5-alkenyl-4-iminohydantoin products from the corresponding starting E- or Z-N?-alkenyl urea, each of which may be formed from the same N-allyl precursor by stereodivergent alkene isomerization. The reaction, formally a nucleophilic substitution at an sp2 carbon atom, allows the direct regioselective incorporation of mono-, di-, tri-, and tetrasubstituted olefins at the alpha-carbon of amino acid derivatives. The initially formed 5-alkenyl iminohydantoins may be hydrolyzed and oxidatively deprotected to yield hydantoins and unsaturated alpha-quaternary amino acids.

Copper-Catalyzed N-Formylation of Amines through Tandem Amination/Hydrolysis/Decarboxylation Reaction of Ethyl Bromodifluoroacetate

Ethyl bromodifluoroacetate (BrCF2COOEt) was first used as the N-formylating reagent in the copper-catalyzed N-formylation of amines. A range of primary, secondary, cyclic arylamines, and aliphatic amines underwent the N-formylation smoothly to furnish the N-formamides in moderate-to-excellent yields.

Development of high-affinity 5-HT3 receptor antagonists. Structure- affinity relationships of novel 1,7-annelated indole derivatives. 1

On the basis of the structures of ondansetron and GR 65,630, its ring- opened C-linked methylimidazole analogue, novel 1,7-annelated indole derivatives were synthesized as potential 5-HT3 antagonists. Receptor binding studies show that all compounds display a high affinity for the 5- HT3 receptors. In both series annelation results in compounds being 7 and 4 times more potent than the references ondansetron and GR 65,630, respectively. Similar to ondansetron, the 1,7-annelated indoles show little stereoselectivity. The (-)-isomers are only slightly more potent than the (+)-isomers. The receptor binding profile of l-10-[(2-methyl-1H-imidazol-1- yl)methyl]-5,6,8,9,10,11-hexahydro-4H-pyrido[3,2,1-jk]carbazol-11-one hydrochloride (24b) (INN cilansetron) shows that the compound displays, besides a high affinity for 5-HT3 receptors (K(i) = 0.19 nM), a weak affinity for sigma-receptors (K(i) = 340 nM), muscarine M1 receptors (K(i) = 910 nM), and 5-HT4 receptors (K(i) = 960 nM) and no affinity (K(i) ? 5000 nM) for all the other receptor types tested (n = 37). The new compounds fit the proposed necessary chemical template for binding: a heteroaromatic ring system, a coplanar carbonyl group, and a nitrogen center at well-defined distances. The enhanced potency of the annelated 1,7-indole derivatives indicates that the extra ring provides a favorable hydrophobic area for interaction with the 5-HT3 receptor site. In vivo cilansetron is more potent and induces less central side effects than ondansetron. At present cilansetron is in clinical trials.

Zinc-Catalyzed Hydroxyl-Directed Regioselective Ring Opening of Aziridines in SN2 Reaction Pathway

In this protocol, a zinc-catalyzed catalytic regioselective ring opening of electronically and sterically unbiased 2,3-aziridinyl alcohols has been accomplished. The directing effect of the hydroxyl moiety enables the selective nucleophilic attack to the C-3 position of 2,3-aziridinyl alcohols with various aromatic amines and thiophenols as nucleophiles. This operationally simple reaction provides convenient access to a variety of amino alcohols and hydroxyl sulfides in excellent regiocontrol. Moreover, simple derivatization of the ring opening product establishes a general strategy to approach internal vicinal diamines in regioselective and diastereomerically pure form.

A concise and efficient synthesis of substituted morpholines

A simple and efficient method has been developed for the synthesis of substituted morpholines by a sequence of coupling, cyclization, and reduction reactions of easily available amino alcohols and alpha-halo acid chlorides. Various mono-, di-, and trisubstituted morpholines, spiro morpholines, and ring-fused morpholines, as well as morpholine homologues, were synthesized in good to excellent yields by a single methodology under similar reaction conditions. The method was also used in a multigram synthesis of (3S)-3-methylmorpholine.

Synthesis and biological evaluation of potential acetylcholinesterase inhibitors based on a benzoxazine core

With the purpose of expanding the structural variety of chemical compounds available as pharmacological tools for the treatment of Alzheimer’s disease, we synthesized and evaluated a novel series of indole-benzoxazinones (Family I) and benzoxazine-arylpiperazine derivatives (Family II) for potential human acetylcholinesterase (hAChE) inhibitory properties. The most active compounds 7a and 7d demonstrated effective inhibitory profiles with Ki values of 20.3 ¡À 0.9 muM and 20.2 ¡À 0.9 muM, respectively. Kinetic inhibition assays showed non-competitive inhibition of AChE by the tested compounds. According to our docking studies, the most active compounds from both series (Families I and II) showed a binding mode similar to donepezil and interact with the same residues.
