A chemoenzymatic methodology has been developed using indium-mediated allylation of heterocyclic aldehydes under aqueous conditions followed by Pseudomonas cepacia lipase-catalyzed enantioselective acylation of racemic homoallylic and homopropargylic alcohols in organic media. It is observed that the lipase immobilized on ceramic particles (PS-C Amano II) catalyzes the resolution in a highly enantioselective
Optically active uracil and chromen-4-one substituted homoallylic alcohols were obtained from the corresponding racemic alcohols by Pseudomonas cepacia lipase catalyzed transesterification in high enantiomeric ratio (E) under mild reaction conditions.
