The results from the baker's yeast-mediated reduction of the acetates 3a-d and the methyl ethers 5a-d were compared with the same biotransformation which converts the α-hydroxy ketones 1a-d into the (R)-diols 2a-d (90–98%ee); the acetates 3a-d afford the (S)-monoacetates 4a-d (72–94% ee) and the methyl ethers 5a-d are reduced to the (R)-monoethers 6a-d (64–76% ce).
将面包师酵母介导的乙酸盐3a-d和甲基醚5a-d还原的结果与将α-羟基酮1a-d转化为(R)-二醇2a-d的相同生物转化进行了比较(90 –98%ee); 醋酸盐3a-d提供(S)-单乙酸盐4a-d(72-94%ee),甲基醚5a-d还原为(R)-单醚6a-d(64-76%ce)。
