Reduction of β-hydroxy ketones to the corresponding 1,3-diols by baker'syeast was investigated, in order to develop methods for simultaneous control over the configurations of multiple stereogenic centres. The reactions were found to be enantiospecific and generally characterised by good diastereoselectivity. Substrates with a substituent at the carbon atom in the α position were also considered.

chemoenzymatic approach (lipase PS from Burkholderia cepacia). These diols were converted into useful chiralsynthons, 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
