In order to determine the chiral purity of 25 it was converted into a lactone by treatment with pTsA in methanol HPLC: Kromasil 5-Amycoat column (EtOH/n-hexane) 25:75, flow rate: 0.7 mL/min, Î = 214 nm). Retention time [min]: 8.817 (major) and 10.092 (minor). The racemic standard was prepared in the same way with racemic γ-hydroxy ester, ee 98 %
