The total synthesis of naphthoquinone natural products isolated from the Bignoniaceae plant family is described. Pinnatal, isopinnatal, sterekunthals A and B, pyranokunthones A and B, and anthrakunthone have been prepared along the lines of a biosynthetic proposal involving pericyclic reactions as key steps. The first case of catalysis in oxa 6pi electrocyclizations is reported.
描述了从紫杉科植物家族中分离出的萘醌天然产物的全合成。Pinnatal、isopinnatal、sterekunthals A 和 B、pyranokunthone A 和 B 以及蒽醌已按照涉及周环反应作为关键步骤的生物合成方案制备。报道了 oxa 6pi 电环化催化的第一个案例。
