Abstract
Treatment of N-acyloxazolidinones with hydroxylamines using samarium triflate as a Lewis acid provides the corresponding hydroxamic acids in 50-98% yields at room temperature. The conversion proceeds with high degree of chemoselectivity and without racemization of chiral centers alpha- to the acyl group. [reaction: see text]Entities:
