摘要

Abstract A novel and efficient method for the one-pot transformation of β-hydroxycarbonyl compounds to α-brominated 1, 3-dicarbonyl compounds is achieved with MoO 2 Cl 2 in the presence of N-bromosuccinimide. All the reactions were carried out under mild conditions and provide good yields of the products. No bromination occurs at benzylic and allylic positions.
