A variety of unsaturated or partly and differentially saturated benzoindolizine derivatives of N-acylphenothiazine 1–3 has been efficiently synthesized by cyclocondensation of acetylenic or olefinic dipolarophiles with azomethine ylide 4 derived from N-acetylisoquinolinium salt 5 flanking a phenothiazine unit.
通过炔属或烯属亲偶极物与源自吩噻嗪单元侧翼的 N-乙酰基异喹啉鎓盐 5 的偶氮甲碱叶立德 4 的环缩合,有效合成了 N-酰基吩噻嗪 1-3 的各种不饱和或部分和差异饱和的苯并吲嗪衍生物。
