Electrophilic cyclizations are one of the major strategies for cyclofunctionalizations of alkenes. Selective selenocyclizations can be performed by adjusting various factors in such reactions. The nature of the electrophile, the counterion, solvents, and external additives coordinating to the electrophilic species are used to control the course of such cyclizations with high degrees of efficiency.
亲电环化是烯烃环官能化的主要策略之一。选择性硒环化可以通过调整此类反应中的各种因素来进行。亲电试剂的性质、抗衡离子、溶剂和与亲电物质配位的外部添加剂用于以高效率控制这种环化过程。我们的研究已经扩展到使用手性硒亲电试剂的立体选择性反应。
