A New Strategy for Pyrrolo[1,2-<i>a</i>][1,4]diazepine Structure Formation
A new method is elaborated for the synthesis of benzo- and thieno[2,3- B]pyrido-annelated pyrrolo[1,2- A][1,4]diazepine skeleton, as a result of recyclization of furfuryl amides of the corresponding aromatic and heteroaromatic acids with an amino group in the ORTHO position. A feature of the method is a simultaneous formation of pyrrole and diazepine rings in the reaction.

We report N-alkylation reactions of pyrrolo[1,2-a][1,4]diazepin-6-ones annulated with a benzene ring or thieno[2,3-b]pyridine system. A range of new N5-substituted pyrrolodiazepines were synthesized, including compounds acting as antidotes against the herbicide 2,4-D.

New Mannich bases were synthesized through an interaction of fused pyrrolo[1,2‐a][1,4]diazepines with secondary amines and formaldehyde. The reaction appears to be regioselective, yielding the monosubstituted products bearing N,N‐dialkylaminomethyl group at position 2 of the pyrrolodiazepine moiety.
新的曼尼希碱是通过稠合的吡咯并[1,2- a ] [1,4]二氮杂with与仲胺和甲醛的相互作用合成的。该反应似乎具有区域选择性,在吡咯并二氮杂moiety部分的2位上生成带有N,N-二烷基氨基甲基基团的单取代产物。
