binfunctional reagents V and ent-V undergo asymmetric aldehyde allylation followed by Ir(I)-catalyzed enantioselective allylic amidation to give orthogonally protected syn- and anti-1,3-aminoalcohols with complete control of absolute and relative stereochemistry. The Mitsunobu reaction of the initial homoallylic alcohol products followed by Ir(I)-catalyzed enantioselective allylic amidation provides
新型手性双功能试剂V和ent - V经历不对称醛烯丙基化,然后Ir(I)催化的对映选择性烯丙基酰胺化,得到正交保护的顺式和反式-1,3-氨基醇,完全控制绝对和相对立体化学。最初的均烯丙基醇产物的Mitsunobu反应,然后进行Ir(I)催化的对映选择性烯丙基酰胺化反应,以高收率和优异的立体选择性提供了正交保护的顺式和反式-1,3-二胺衍生物。
