摘要

Condensation of 1-bromo-2-naphthalenecarboxylic acid (9) with 7-methoxy-2, 2-dimethyl- 2H-1-benzopyran-5-ylamine (13) followed by acid-mediated cyclization afforded 6-methoxy- 3, 3-dimethyl-3, 14-dihydro-7H-benzo [c] pyrano [3, 2-h] acridin-7-one (15), which was further methylated into 6-methoxy-3, 3, 14-trimethyl-3, 14-dihydro-7H-benzo [c] pyrano [3, 2- h] acridin-7-one (benzo [c] acronycine)(3) and 6, 7-dimethoxy-3, 3-dimethyl-3H-benzo [c] ...
