摘要

Stilbeneylsydnone derivatives were synthesized by a sequence of reactions in good yields. Irradiation of 3-stilbeneyl-4-methylsydnone 4 gives 1H-1, 2-benzodiazepine derivative 7 as the main product along with 2-methylquinoline derivative 20. Irradiation of 3-stilbeneyl-4- phenylsydnone 5 afforded only 1H-1, 2-benzodiazepine derivative 8 whereas on irradiation of 4-unsubstituted 3-stilbeneylsydnone 3 no benzodiazepine derivative was detected. An ...
