New phosphoramidites were applied as chiral ligands in the Cu-catalyzed allylic alkylation with dialkylzinc reagents. A variety of substrates, reagents and chiral ligands were screened, resulting in improved catalytic methodology for allylic bromides in which enantioselectivities up to 88% were reached.
将新的亚磷酰胺用作手性配体,用二烷基锌试剂在铜催化的烯丙基烷基化反应中使用。筛选了各种底物,试剂和手性配体,从而改进了烯丙基溴的催化方法,其中对映选择性高达88%。
