Stereoselective synthesis of d-5-homo-4-selenoribose, serving as a versatile intermediate for the synthesis of 4′-selenonucleosides 12a–c, was accomplished using Sharpless asymmetric epoxidation, regioselective cleavage of the α,β-epoxide, and stereoselective reduction of the ketone as the key steps.
d -5 -homo-4-selenoribose的立体选择性合成,是合成4'-selenonucleosides 12a – c的通用中间体,使用Sharpless不对称环氧化,α,β-环氧的区域选择性裂解和立体选择性还原来完成酮是关键步骤。
