The asymmetric dihydroxylation of α,β- and β,γ-unsaturated amides affords the corresponding diols in good yields and excellent enantiomeric excesses. However, both N,N-diakyl and N-methoxy-N-methyl α,β and β,γ-unsaturated amides require a Modified-AD-mix™ formulation to achieve good catalytic turnover rates
α,β-和β,γ-不饱和酰胺的不对称二羟基化以良好的收率和优异的对映体过量提供了相应的二醇。但是,N,N-二烷基和N-甲氧基-N-甲基α,β和β,γ-不饱和酰胺均需要改性AD-mix ™配方才能实现良好的催化周转率
