The synthesis of 10H-pyrrolo[1,2-a]thieno[3,4-e][1,4]diazepin-5(4H)-one (16) and some derivatives are described from methyl 3-bromomethylthiophene-4-carboxylate (5). The key step of these sequences is the intramolecular cyclization of the carbonylazides 12 and 13.
从甲基3-溴甲基噻吩-中描述了10 H-吡咯并[1,2- a ]噻吩并[3,4- e ] [1,4]二氮杂ze-5(4 H)-one(16)和一些衍生物的合成。 4-羧酸盐(5)。这些序列的关键步骤是羰基叠氮化物12和13的分子内环化。
