In Os-catalysed asymmetric dihydroxylation using NMO as a co-oxidant, the combination of an ionic liquid and the new bis-cinchona alkaloid 2 generated in situ from (QN)2PHAL during reaction provided a simple and practical approach to the recycling of both catalytic components (osmium tetroxide and chiral ligand).
Catalytic asymmetric dihydroxylation of olefins with recyclable osmate-exchanged chloroapatite catalyst

An osmate-exchanged chloroapatite (CAP-OsO4) catalyst was prepared by an ion-exchange technique. CAP-OsO4 efficiently catalyses asymmetric dihydroxylation of olefins including α,β-unsaturated esters and amides to afford the corresponding diols in high yields and enantioselectivities. The catalyst was reused for several cycles with consistent activity.
Lipase-catalyzed transesterification as a practical route to homochiral syn-1,2-diols. The synthesis of the taxol side chain

syn-2,3-Dihydoxy-3-phenyl-propanoic acid methyl ester (1a) and its simple derivatives (1b-e) are efficiently resolved in LPS-catalyzed transesterification, leading to the synthesis of the taxol side chain and analogs from both resolved enantiomers.
