Enzymatic Desymmetrisation of Prochiral
Herein we present the biocatalysed preparation of a 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 li...

Summary: | Herein we present the biocatalysed preparation of a 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 carbonates. The reactions were conducted at different temperatures, for different reaction times and with variable co-solvent systems to evaluate the effects 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) when conducting the reaction solventless at 75 °C. |
