The Michael adducts of arylacetonitrile enolates and unsaturated esters may be converted to fused phenolic systems by the following sequence: ester hydrolysis, Na/NH3 reductive elimination of cyanide, Friedel-Crafts ring closure, and oxidation. The construction of linear polycyclic systems by this annelation procedure is illustrated by the regiospecific syntheses of 7-methyljuglone and dl-7,9,ll-trideoxydaunomy-
芳基乙腈烯醇酸酯和不饱和酯的迈克尔加合物可以通过以下顺序转化为稠合酚醛系统:酯水解,Na / NH 3还原性氰化物的消除,Friedel-Crafts闭环和氧化。通过该脱核方法的线性多环系统的构建通过7-甲基胡格隆和dl-7,9,ll-三苯氧基十二烷二酮的区域特异性合成来说明。
