Abstract Candida antarctica (CAL‐B) lipase‐catalyzed resolution of 1,3‐dialkyl‐3‐hydroxymethyl oxindoles has been performed to obtain ( R )‐1,3‐dialkyl‐3‐acetoxymethyl oxindoles with up to 99% ee and ( S )‐1,3‐dialkyl‐3‐hydroxymethyl oxindoles with up to 78% ee using vinyl acetate as acylating agent...
