The cyclization of a number of functionalized polyenes with mercuric triflate - N,N-dimethylaniline complex (Nishizawa's reagent) to give bicyclic or tricyclic products has been studied. Suitably positioned internal nucleophiles, such as carbonyl, hydroxy and β-ketoester groups were found to participate to varying extent, in the termination of these cyclizations.
已经研究了使用三氟甲磺酸汞-N,N-二甲基苯胺络合物(西泽试剂)将许多官能化多烯环化以生成双环或三环产物的方法。发现合适定位的内部亲核试剂,例如羰基,羟基和β-酮酸酯基团在这些环化的终止中以不同程度参与。
