摘要

9, 10-Disubstituted protoberberines were synthesised by photolysis of the corresponding bromo-enamides in high yields. The products were converted into (±)-xylopinine,(±)- schefferine,(±)-nandinine,(±)-corydaline, and (±)-thalictricavine. Xylopinine was also synthesised, together with the corresponding styrene der
