acetates and derivatives were synthesized by an efficient two-step protocol that employs readily available terminal alkenes as starting materials. This method is highly regio- and stereoselective, affording the linear (E)- isomer as the sole adduct. This process tolerates several functional groups including halogen-containing molecules, and it is general for weak oxygen, carbon, nitrogen, and sulfur
通过有效的两步方案,使用容易获得的末端烯烃作为起始原料,合成了多种烯丙基乙酸酯和衍生物。该方法是高度区域和立体选择性的,提供线性(E)-异构体作为唯一的加合物。该过程可耐受包括含卤素分子在内的几个官能团,通常用于弱氧,碳,氮和硫亲核试剂。此外,以良好至优异的产率获得了加合物。
