Abstract A facile method for the synthesis of (2R,3R)‐1,4‐dimethoxy‐1,1,4,4‐tetrasubstituted‐2,3‐butanediols involving oxidative cleavage of benzylidene acetal as a key step is described. These sterically hindered diols unusually formed cyclic sulfites as the major product under methanesulfonylation reaction conditions.
摘要描述了一种合成 (2R,3R)-1,4-二甲氧基-1,1,4,4-四取代-2,3-丁二醇的简便方法,该方法涉及作为关键步骤的亚苄基乙缩醛的氧化裂解。这些空间位阻二醇在甲磺酰化反应条件下异常形成环状亚硫酸盐作为主要产物。
