Solid-state and solvent-free synthesis of azines, pyrazoles, and pyridazinones using solid hydrazine

Azines, pyrazoles, and pyridazinones were isolated as the sole products in high yields (>97%) by grinding solid hydrazine (H3N +NHCO2-) with di-carbonyl compounds or by their reaction in the absence of solvent. Neither catalysts nor additives were needed to promote the reactions. The solid-state and solvent-free reactions proceeded under ambient conditions and did not produce any wastes other than water and carbon dioxide. They are operationally easy, environmentally safe, and readily scalable, allowing for highly selective synthesis of compounds containing the hydrazine motif. Copyright

Reversible and persistent electrical bistability in single crystals of a self-assembled pi-conjugated tetraaryl system: A submicrometer scale electrical characterization

A new pi-conjugated electroactive 4,4?-bipyridinium that bears two pyridazone self-complementary units was prepared and characterized. The new system readily assembles and forms at least two stable charge-transfer crystalline structures having a thermal population of unpaired electrons. The crystals of one phase exhibit electrical bistability, displaying either high (ON) and low (OFF) conductivity, at the same applied bias, depending on the electrical history of the system. The relation between the supramolecular structure of the crystals and their electrical properties is also discussed.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Quality Control of 3,6-Dichloropyridazine, you can also check out more blogs about141-30-0

New non-peptide endothelin-a receptor antagonists: Synthesis, biological properties, and structure-activity relationships of 5-(dimethylamino)-N- pyridyl-, -N-pyrimidinyl-, -N-pyridazinyl-, and -N-pyrazinyl-1- naphthalenesulfonamides

Use of automated synthesis led to the discovery of several 6-membered nitrogen heterocycles as replacements for the N-isoxazolyl substituent present in the 1-naphthalenesulfonamide endothelin-A (ETA) antagonist 5- (dimethylamino)-N-(3,4-dimethyl-5-isoxazolyl)-1-naphthalenesulfonamide (BMS 182874). In each of these heterocycles, a small substituent such as halogen para to the position of attachment to the sulfonamide nitrogen atom was found to be advantageous for ETA receptor affinity. Of these heterocycles, 2- pyrazines offered the greatest scope for improving receptor affinity. Optimization of the substituents at the 3- and 5-positions in the pyrazine ring led to potent, ET(A)-selective compounds such as 5-(dimethylamino)-N- (5-chloro-3-methoxy-2-pyrazinyl)-1-naphthalenesulfonamide (7m, ET(A) pIC50 8.1). When dosed orally at 10 mg/kg to conscious, normotensive rats infused with big ET-1, compounds such as 7m showed significant inhibition of the pressor response with a duration of effect lasting for the 5-h course of the experiment.

Stereoselective micellar catalysis. Reactions of amino-acid ester derivatives with N-acyl-L-histidine in micelles

Mixed micelles of the N-acyl-L-histidines (I) and cetyltrimethylammonium bromide (CTABr) are effective stereoselective catalysts for cleavage of the enantiomeric amino-acid ester derivatives (II). The rate enhancements and stereoselective effects depend on the hydrophobicity of (I) in micelles, and an increase in the chain length of the acyl part of (I) increases both the reaction rates and the enantiomer rate ratio. Mixed micelles with anionic and nonionic surfactants are relatively less effective stereoselective catalysts. Kinetic analysis indicates that the stereoselectivity in mixed micelles is mainly determined by catalytic acyl transfer to the optically active imidazole group of (I).
