An Efficient 1,2-Chelation-Controlled Reduction of Protected Hydroxy Ketones via Red-Al
摘要:
[GRAPHICS]In this paper, we have demonstrated that Red-Al is an efficient chelation-controlled reducing reagent for acyclic acetal (i.e., MOM, MEM, SEM, and BOM) protected alpha-hydroxy ketones. Typically, diastereomeric ratios (dr) ranged from 5 to 20:1 for the 1,2-anti-diols in good to excellent yields.
