An efficient catalytic four-component reaction of carbonyl compounds (or acetals/ketals), benzyl chloroformate (CbzCl), 1,1,1,3,3,3-hexamethyldisilazane (HMDS), and allyltrimethylsilane has been successfully developed to produce Cbz-protected homoallylic amines in the presence of 5 mol % of iron(II) sulfate heptahydrate (FeSO4·7H2O), an inexpensive and environmentally friendly catalyst, at room temperature
已成功开发了羰基化合物(或缩醛/缩酮),氯甲酸苄酯(CbzCl),1,1,1,3,3,3-六甲基二硅氮烷(HMDS)和烯丙基三甲基硅烷的高效催化四组分反应,可生产Cbz-在室温下,在5摩尔%的七水合硫酸铁(II)(FeSO 4 ·7H 2 O)(一种廉价的环境友好型催化剂)的存在下,保护被保护的均烯丙基胺。
