Abstract

"PROCESSO PARA A PREPARAçãO DE éSTERES DO áCIDO 6,8-DIIDROXIOCTANóICO ENANTIOMERICAMENTE PUROS ATRAVéS DE HIDROGENAçãO CATALìTICA ASSIMéTRICA". A invenção refere-se a um processo para a preparação de compostos de fórmula geral I em que R^ 1^ representa um grupo C~ 1~-C~ 20~-alquila, um grupo C~ 3~-C~ 12~-cicloalquila, um grupo C~ 7~-C~ 12~-aralquila ou um grupo arila mono ou binuclear, em que uma cetona de fórmula II em que R^ 1^ é como definido acima, é submetida a hidrogenação assimétrica.
