Kinetic resolution of rac-1,2-diols using the biocatalyst Burkholderia cepacia lipase (BCL) immobilized on a biodegradable binary blend support of hydroxypropyl methyl cellulose(HPMC)/polyvinyl alcohol (PVA) has been investigated. The immobilization technique improved enzyme activity significantly and it has excellent recyclability with good yield and enantiomeric excess values up to the studied range...
The synthesis of optically active β-triazolyl amino alcohols was carried out via ruthenium catalyzed asymmetric transfer hydrogenation of α-triazolyl amino alkanones. This reaction proceeds under mild reaction conditions with up to 99% yield and 99.9% enantiomeric excess (ee). This protocol was applied to the synthesis of an enantiopure antitubercular agent and its arylated product with retention...
