Enantiomerically enriched secondary organoboronates containing β‐carbonyl functional groups have been prepared using an unprecedented organocatalytic system (see scheme). The use of chiral tertiary phosphorus compounds induced ee values of up to 95 % in the absence of transition metals.
使用史无前例的有机催化体系制备了含有β-羰基官能团的对映体富集的仲有机硼酸酯(参见方案)。在不存在过渡金属的情况下,使用手性叔磷化合物可导致ee值高达95%。
