A new approach to the synthesis of antitumor benzophenanthridine alkaloids. Formal synthesis of nitidine
摘要:
The synthesis of benzophenanthridine alkaloids by an efficient new convergent strategy based on the Diels-Alder reaction between an alpha-pyrone and an aryne is described. With minor modifications, norbenzophenanthridines and phenanthridines and their 12-amino derivatives were obtained in good overall yields.
