Reduction of ethyl 4-t-butoxy-3-oxobutanoate with fermenting yeast yields (R)-ethyl 4-t-butoxy-3-hydroxybutanoate in 97% e.e. Since the protective group is readily removed from the product of reduction, the present procedure provides a simple entry to the "world of chiral blocks" formally derived from (R)-malic acid.
用发酵酵母还原 4-t-丁氧基-3-氧代丁酸乙酯,可得到(R)-4-t-丁氧基-3-羟基丁酸乙酯,纯度为 97%。由于保护基团很容易从还原产物中去除,因此本程序为正式从(R)-苹果酸中提取的 "手性嵌段世界 "提供了一个简单的入口。
