摘要
The optical active fork glycerinol (2,2-dimethyl-1,3-dioxolane- 4-methanol)(1) was synthesized with L-serine(2) as the starting material. L-glyceric acid(3) was synthesized via the nitrosation of (2). With TsOH as the catalyst and 4A molecular sieve as the dehydration agent, L-2,3-O-isopropylidene-glycerate(5) was (directly) prepared from (3), 2,2′-dimethoxypropane and methanol without isolating the intermediate. Instead of (LiAlH4), NaBH4 was used to reduce (5) to the final compound (1). The total yield of was 47%.
