3-b]pyridine-2-carboxamides containing a phenyl or hetaryl moiety at position 4 were synthesized. The influence of the nature of the substituent on the direction of intramolecular cyclization with the participation of nitrene was studied. Novel pyrido[3',2':4,5]thieno[3,2-b][1,5]benzodiazepin-11-ones and benzo[c]thieno[2,3,4-ij][2,7]naphthyridines were synthesized.
合成了一系列在4位含有苯基或杂芳基的叔3-叠氮基-N-苯基噻吩并[2,3 - b ]吡啶-2-羧酰胺。研究了取代基性质对分子间环化方向的影响以及氮的参与。新颖的吡啶基[3',2':4,5]噻吩并[3,2-b] [1,5]苯并二氮杂-1-酮和苯并[ c ]噻吩并[2,3,4- ij ] [2,7合成了萘啶。
