A unique base-dependent diastereoselective synthesis of polysubstituted pyrrolidines/dihydropyrroles from chalcone, benzylamine and benzaldehyde was described. After oxidized by DDQ, the resulting tetra-substituted pyrroles were found to be light-sensitive and undergo oxidative ring-opening reaction to yield the enamides upon UV irradiation.

多取代吡咯烷/二氢吡咯的非对映选择性合成：多取代吡咯的光化学性质

描述了从查耳酮、苄胺和苯甲醛中独特的碱依赖性非对映选择性合成多取代吡咯烷/二氢吡咯。经 DDQ 氧化后，发现所得四取代吡咯对光敏感，并在紫外线照射下发生氧化开环反应以产生烯酰胺。
