英文摘要 | Treatment of 14-methylsulfonyl pseudaconine 3 with DMF-NaOH at 150 degreesC for 10 h afforded the desired C-nor and 12,13-seco norditerpenoid alkaloids 16 alpha -methoxyl ketone 7 (70%) and 16 beta -methoxyl ketone 8 (15%) as a pair of epimers. Reaction of 7 with Br-2-HOAc at room temperature for 1.5-2 h produced the phenols 9 (40%), 10 (10%) and 13 (29%). Whereas, treatment of 8 with Br-2-HOAc under same conditions as the case for 7 gave phenolic compound 9 (38%) besides the by-product alpha -bromoketone 14 (25%). (C) 2001 Elsevier Science Ltd.
