Abstract
Herein we present the biocatalysed preparation of mono-N-carbamate-protected precursor of antitumoral Nutlin-3a, through enantioselective alkoxycarbonylation of meso-1,2-disubstituted-1,2-diaminoethane, using enzyme lipases and dialkyl carbonates as acylating agents. A series of supported or free lipase enzymes were screened in combination with commercially available diallyl-, diethyl and dimethyl- carbonate. The reactions were conducted at different temperatures, reaction times and with variable co-solvent systems to evaluate the effect on the enzyme catalytic activity. The best results in terms of conversion, enantiomeric excess and yield were obtained when lipase from Candida antarctica B (CAL-B) was used with diallyl carbonate (DAC) conducting the reaction solventless at 75 °C.
