Cycloaddition reactions of isoquinoline-pyrroline-2,3-dione and .beta.-carboline-pyrroline-2,3-dione with benzyne. Total synthesis of 8-oxypseudopalmatine and decarbomethoxydihydrogambirtannine
摘要:
The formation of the skeletons of protoberberines and dehydroyohimbanes by cycloaddition between pyrrolinediones and arynes is described. Total syntheses of 8-oxypseudopalmatine and decarbomethoxydihydrogambirtannine were performed.
