Special Issue Information

Dear Colleagues,

Natural catalysts such as enzymes often outperform synthetic catalysts, both kinetically and in terms of selectivity (e.g., enantioselectivity). Biocatalysis can usually be carried out under mild conditions (e.g., ambient temperature and pressure, aqueous and organic solutions), and the catalysts used are generally biodegradable, biocompatible, and renewable, making these catalytic systems highly attractive for environmentally benign processes. A major application of enzymes, which has already gained industrial importance, are kinetic resolutions of racemic substrates. What makes enzymatic resolution attractive is the easy access to racemic substrates by means of many chemical methodologies in combination with the high efficiency and selectivity provided by the biocatalyst. In spite of the achievements in these fields, numerous challenges still exist.

This Special Issue will discuss recent developments in the preparation of enantiopure substances by means of enantioselective enzymatic resolutions and will include strategies that involve enzymatic catalysis in combination with chemical, photochemical, mechanochemical, and other types of non-traditional activation. A further focus of this special Issue will also be on dynamic kinetic resolution processes combining enzymatic resolutions with novel types of chemocatalytic or enzymatic racemization steps.

Lipase-Catalyzed Kinetic Resolution of Alcohols as Intermediates for the Synthesis of Heart Rate Reducing Agent Ivabradine

Ivabradine (Corlanor®), is a chiral benzocycloalkane currently employed and commercialized for the treatment of chronic stable angina pectoris and for the reduction in sinus tachycardia. The eutomer (S)-ivabradine is usually produced via chiral resolution of intermediates, by employing enantiopure auxiliary molecules or through preparative chiral HPLC separations. Recently, more sustainable biocatalytic approaches have been reported in literature for the preparation of the chiral amine precursor. In this work, we report on a novel biocatalyzed pathway, via a resolution study of a key alcohol intermediate used as a precursor of the chiral amine. After screening several enzymatic reaction conditions, employing different lipases and esterases both for the esterification and hydrolysis reactions, the best result was achieved with Pseudomonas cepacia Lipase and the final product was obtained in up to 96:4 enantiomeric ratio (e.r.) of an ivabradine alcohol precursor. This enantiomer was then efficiently converted into the desired amine in a facile three step synthetic sequence. Full article

Title: Synthesis of Optically Active Piperidines Using Hydrolase
Authors: Koichi Mitsukura
Affiliation: Department of Chemistry and Biomolecular Science, Faculty of Engineering, Gifu University 1-1 Yanagido, Gifu 501-1193, Japan
Abstract: We have found a bacterium with an (S)-selective hydrolase that convert racemic N-acyl-2-methylpiperidine to (S)-2-methylpiperidine. In the present study, we describe the characterization and substrate specificity of the purified (S)-selective hydrolase.
