Enzymatic Kinetic Resolution of Secondary Alcohols Using an Ionic Anhydride Generated In Situ
Abstract We developed a method for the resolution of secondary alcohols using an ionic anhydride acylating agent prepared directly in the reaction medium containing the biocatalyst Candida antarctica lipase B (CALB). NMR studies showed that mixing all components at the same time does not interfere w...
