An interesting new route to access 3,4‐dihydrothiopyrano[3,4‐b]indol‐1(9H)‐imines through a tandem Friedel–Crafts alkylation and a Thia‐Michael addition has been developed. In addition, the described methodology is also applicable to access the less explored tetrahydro‐1H‐thiepino[3,4‐b]indole scaffolds. The strategy has atom economy, various functional group tolerance and wide substrate scope as the
已经开发了一种有趣的新途径,可通过串联的Friedel-Crafts烷基化反应和Thia-Michael加成反应获得3,4-二氢硫代吡喃并[3,4- b ]吲哚-1(9 H)-亚胺。此外,所描述的方法学也适用于研究较少的四氢-1 H - thiepino [3,4- b ]吲哚支架。该策略以原子经济,各种官能团耐受性和广泛的底物范围为关键特征。
