The cycloaddition of enamines with electrophilic gem-dimethylcyclopropenes followed by solvolytic ring cleavage of the 2-amino bicyclo [2.1.0] pentane adducts, leads to gem-dimethylcyclopentene derivatives. This novel reaction sequence is illustrated by the synthesis of (±)-Hirsutene, a natural linear triquinane, starting from 3,3-dimethylcyano-cyclopropene and the diquinane enamine 3.
烯胺与亲电的宝石-二甲基环丙烯的环加成,然后2-氨基双环[2.1.0]戊烷加合物的溶剂化环裂解,生成宝石-二甲基环戊烯衍生物。这种新颖的反应顺序可以通过合成天然的线性三喹烷(±)-Hirsutene(3,3-二甲基氰基-环丙烯和二喹烷烯胺3)来说明。
