Intramolecular Diels-Alder reaction of l-azadienes was conducted by heating the α,β-unsaturated amides (2a ∼ d and 6) in the presence of trimethyl- chlorosilane, triethylamine and zinc chloride to give benzo- and indolo[a]- quinolizidines (5a ∼ e and 7).
通过在三甲基氯硅烷,三乙胺和氯化锌的存在下加热α,β-不饱和酰胺(2a〜d和6)进行l-氮杂二烯的分子内Diels-Alder反应,得到苯并-和吲哚[a]-喹喔啉类(5a〜e和7)。
