see text] Cyclizations of substituted (E)-1-nitro-1,7,9-decatrienes under thermal and Lewis acid conditions have led to the formation of decalin ring systems with excellent endo selectivity. This strategy has been applied to the synthesis of the AB ring system of norzoanthamine.
在热和路易斯酸条件下,取代的(E)-1-硝基-1,7,9-癸二烯环化导致形成具有极高内选择性的十氢化萘环系。该策略已应用于去甲乙胺的AB环系统的合成。
