该中间体在本合成路线中的序号：(XLII)The key dihydroxy ester intermediate (XIII) was also obtained by asymmetric hydrogenation of hydroxy ketoester (XLIII) in the presence of (S)-BINAP-dichlororuthenium catalyst. The precursor hydroxy ketoester (XLIII) was prepared by two alternative procedures. In one method, the racemic dihydroxy ester (XLII) was selectively oxidized to (XLIII) by means of NaOCl. In another method, the unsaturated keto ester (XLIV) was epoxidized by means of sodium percarbonate, and the resultant epoxide (XLV) was then reduced to the hydroxy ketoester (XLIII) by catalytic hydrogenation over PtO2.
