“…Other works used Baker's yeast immobilized on chrysotile for the reduction of phenylketones , α-haloacetophenones (Carvalho et al 1991, Aleixo et al 1993, and the enantioselective synthesis of (R)-(-)-1-phenylethanolamines (Brenelli et al 1992). Lipase from Candida cylindracea was also immobilized on chrysotile and used successfully in organic synthesis (Lima et al 1996).…”

In the present work, the ester synthesis in organic media catalyzed by lipases immobilized on chrysotile was studied. Lipases of different sources (Mucor javanicus, Pseudomonas cepacia, Rhizopus oryzae, Aspergillus niger and Candida rugosa) were immobilized on chrysotile, an inexpensive magnesium silicate, and used for esterification of hexanoic, octanoic and lauric acid with methanol, ethanol, 1-butanol and 1-octanol at 25 • C in hexane as solvent. The best results were obtained with Mucor javanicus lipase and lauric acid giving yields of 62-97% of ester.

The Application of Biocatalysis in the Preparation and Resolution of Morita‐Baylis‐Hillman Adducts and Their Derivatives

et al. 2021

The Morita-Baylis-Hillman (MBH) reaction affords highly functionalised allylic alcohols containing a new stereogenic centre. These MBH adducts are very versatile and have been transformed into a large range of products, some of which have medicinal potential. Several examples of asymmetric syntheses of MBH adducts have been reported, although a generally applicable method remains to be developed. Biocatalytic approaches for the synthesis and enzymatic kinetic resolution of MBH adducts have been reported, and are discussed in detail in this review. Enzymes able to catalyse the asymmetric MBH reaction have been identified, but selectivity and efficiency have generally been low. Lipases, esterases and nitrile-converting enzymes have all been successfully applied in the resolution of MBH adducts, with excellent selectivity being realised in most cases.
