Lipase-catalyzed poly- and monotransesterification reactions were used in kinetic separations of a commercial mixture of cis,trans-1,4-Cyclohexanedimethanol (cas 105-08-8). The reactions were performed with lipases from various sources and with mono- and diesters as the acylating reagents. In a series of monotransesterifications, the highest diastereoselectivity (1:6.5) was obtained with β-chloroethyl hydrocinnamate as the acyl donor and lipase from Pseudomonas fluorescens. Polycondensations with fumarate esters using lipase from porcine pancreas afforded moderate diastereoselectivity (about 1:4.5) for the cis/trans monocondensate, and markedly increased diastereoselectivity (about 1:24) for the cis/trans dicondensate product.
