procedure for the synthesis of functionalized allyl dithiocarbamates is developed. The Baylis–Hillman (BH) reaction of aromatic (heteroaromatic) aldehydes and activated alkenes using DABCO, followed by acetylation of BH adducts with acetic anhydride in the presence of a catalytic amount of DMAP, and nucleophilic substitution reaction by in situ prepared dithiocarbamates from amines and CS2 are three
摘要 开发了一种用于合成功能化的二硫代氨基甲酸烯丙酯的一锅、伪五组分、高非对映选择性和温和的合成方法。芳族(杂芳族)醛和活化烯烃使用 DABCO 进行 Baylis-Hillman (BH) 反应,然后在催化量的 DMAP 存在下用乙酸酐乙酰化 BH 加合物,以及由胺原位制备二硫代氨基甲酸酯的亲核取代反应和 CS2 是该协议的三个步骤。图形概要
