2-Diols are extremely useful building blocks in organic synthesis. Hypervalent iodine reagents are useful for the vicinal dihydroxylation of olefins to give 1,2-diols under metal-free conditions, but strongly acidic promoters are often required. Herein, we report a catalytic vicinal dioxygenation of olefins with hypervalent iodine reagents using Lewis bases as catalysts. The conditions are mild and compatible
1,2-二醇是有机合成中极其有用的组成部分。高价碘试剂可用于在无金属条件下将烯烃邻位二羟基化生成 1,2-二醇,但通常需要强酸性促进剂。在此,我们报告了使用路易斯碱作为催化剂,烯烃与高价碘试剂的催化邻位双氧化反应。条件温和,可与各种官能团相容。
