Enantioselective epoxidation of β,β-disubstituted enamides with aqueous hydrogen peroxide and a novel manganese catalyst is described. Epoxidation is stereospecific and proceeds fast under mild conditions. Amides are disclosed as key functional groups to enable high enantioselectivity.
描述了用过氧化氢水溶液和新型锰催化剂对β,β-二取代的酰胺进行对映选择性环氧化。环氧化是立体定向的,在温和条件下快速进行。酰胺被公开为实现高对映选择性的关键官能团。
