synthesis of the chiral camphor derived γ-amino thiol ligand 17 and its application in catalytic enantioselective carbon-carbon forming reactions through the addition of organozinc reagents to carbonyl compounds is described. The catalytic activity and enantioselectivity of ligand 17 is demonstrated in the enantioselective addition of various organozinc reagents to aldehydes and ketoesters, offering the corresponding
在本文中,描述了手性樟脑衍生的γ-氨基硫醇配体17的设计和合成,以及通过向羰基化合物中添加有机锌试剂在催化对映选择性碳-碳形成反应中的应用。配体17的催化活性和对映选择性通过将各种有机锌试剂对映选择性加成到醛和酮酯中得到证明,从而以高收率和对映选择性提供相应的醇。还讨论了巯基在有机锌与醛的高度对映选择性1,2加成反应中的作用。
