The selenium induced cyclofunctionalization of N-protected 3-hydroxy-4-pentenylamine occurs regio- and steroselectively to give N-protected cis-2-(selenomethyl)-3-hydroxypyrrolidines in high yield. The rate of reaction and degree of stereoselectivity is shown to be dependent on the nature of the selenium reagent, reaction temperature and solvent.
硒诱导的N-保护的3-羟基-4-戊烯基胺的环官能化在区域和立体选择性地发生,从而以高收率得到N-保护的顺式-2-(硒代甲基)-3-羟基吡咯烷。显示反应速率和立体选择性程度取决于硒试剂的性质,反应温度和溶剂。
