英文摘要
Total syntheses of the nor-type of benzo[c]phenanthridine alkaloids, nornitidine, noravicine, isodecarine, norchelerythrine, norsanguinarine, and zanthoxyline, and benzo[c]phenanthridine alkaloids, nitidine, avicine, sanguinarine, chelerythrine and broussonpapyrine were achieved. The key step was the construction of tetracyclic 11,12-dihydrobenzo[c]phenanthridine using a microwave-assisted electrocyclic reaction of the 2-cycloalkenylbenzaldoxime methyl ether as an aza 6π-electron system, which was derived in two steps from a Suzuk-Miyaura cross-coupling reaction of 2-brombenzaldehyde with (3,4-dihydro-6,7-methylenedioxynaphthyl)boronic acid pinacol ester. In addition, the exact structure of broussonpapyrine was determined to be chelerythrine by NMR spectral analysis.
