Reactions of 5-Hydroxymethyl-1H-indole-4,7-dione with Enamines for the First Construction of 1H,5H-Pyrano[3,4-f]indole-4,9-dione Derivatives
摘要:
5-Hydroxymethyl-1-methyl-2,3-diphenyl-IH-indole-4,7-dione (4) was synthesized and the tandem Michael addition/cyclization sequence between this indolequinone and enamines has been used to construct title pyranoindolequinone derivatives (6), (7), and (9).
