A novel method is reported for the synthesis of (±)-trans-10,11-dihydroxy-5,6,6a,7,8,12b-hexahydrobenzo[a]phenanthridine (dihydrexidine, 6b) employing as a key step the cyclization of the acid chloride of 3b, via decarbonylation, to the hexahydrobenzo[a]phenanthridine 4b.
报道了一种新的方法,用于合成(±)-trans-10,11-dihydroxy-5,6,6a,7,8,12b-六氢苯并[a]菲啶(dihydrexidine,6b),这是环化的关键步骤通过脱羰,将3b的酰氯生成六氢苯并[a]菲啶4b。
