The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 3,5-Dimethyl-4-nitropyridine 1-oxide, is researched, Molecular C7H8N2O3, CAS is 14248-66-9, about Studies on diazepines. XXVI. Syntheses of 6H-1,4-diazepines and 1-acyl-1H-1,4-diazepines from 4-pyridyl azides, the main research direction is photochem ring enlargement azidopyridine; methoxydiazepine; diazepine methoxy; acylmethoxydiazepine.Recommanded Product: 3,5-Dimethyl-4-nitropyridine 1-oxide.
Photolysis of 4-azidopyridines I (R-R3 = H, Me) in the presence of methoxide resulted in ring expansion to give 5-methoxy-6H-1,4-diazepines II (R-R3 = H, Me), presumably via azirine intermediates derived from the initially formed singlet pyridylnitrenes. Treatment of II (R-R3 = H) with R4COCl (R4 = Ph, Me, EtO) in pyridine afforded the 1-acyldiazepines III (R4 = Ph, Me, EtO), whose structures were confirmed by means of thermal and photochem. reactions.
