Reduction of α-benzyloxy acetylenic ketones with zinc borohydride afforded the erythro-acetylenic vicinal diols in 95% stereoselectivity, while reduction with K-selectride gave the isomeric threo-diols in 90% stereoselectivity.
用硼氢化锌还原α-苄氧基炔基酮可得到立体选择性为95%的赤-炔邻位二醇,而用K-selectride还原可得到90%立体选择性为异构的苏-二醇。
