chemoenzymatic approach (lipase PS from Burkholderia cepacia). These diols were converted into useful chiral synthons, which could be considered homologues of glyceraldehyde and glyceric acid acetonides. Applications of these synthons to the de novo synthesis of sugars and preparation of conagenin carboxylic moiety were shown. Hydroxy ketone 4 was chosen as a model system for another synthetic evolution: it
对映体纯的1,3-二醇1 - 3通过(洋葱伯克霍尔德氏菌的脂肪酶PS)一个化学酶促方法获得。这些二醇被转化为有用的手性合成子,其可以被认为是甘油醛和甘油酸丙酮化物的同系物。显示了这些合成子在糖的从头合成和刀豆蛋白羧基部分的制备中的应用。选择了羟基酮4作为另一种合成进化的模型系统:通过酶促拆分以对映体纯的形式获得了羟基酮4,并将其转化为手性四氢吡喃,例如商业香料Gyrane的立体异构体。
