A new class of rhodium carboxylate complexes, which contain phenylacetate ligands substituted with bulky chiral alkoxy substituents, has been prepared, and the application of these complexes in some representative carbene transfer processes of α-diazocarbonyl compounds is described. Good enantioselectivity is obtained across a range of transformations.
制备了一类新的羧酸铑配合物,其中含有被大手性烷氧基取代基取代的苯乙酸配体,并描述了这些配合物在α-重氮羰基化合物的一些代表性卡宾转移过程中的应用。通过一系列的转化可以获得良好的对映选择性。
