Abstract
Amino-Claisen rearrangement of 4-(2-vinyl- azetidino or aziridino)-5-m ethoxy-1,2-benzoquinones 3a,b selectively gives rise to the new tetrah ydroazocino - quinone 4a or dihydroazepino - quinone 4b respectively. Based on paramethoxyphenol as starting material, overall yields for th e 3 steps synthesis of heterobicyclic quinones 4a, b are 58 and 52%.
