Abstract
Abstract Vinyl 2-chloroacetate was used as an efficient acyl donor for enantioselective acylation of racemic 1,2,3,4-tetrahydroquinolin-4-ols and 2,3,4,5-tetrahydro-1H-benzo[b]azepin-5-ols with Novozyme 435 lipase. Two enantiocomplimentary tetrahydroquinolin-4-ol or tetrahydro-1H-benzo[b]azepin-5-ol derivatives could be smoothly obtained in good to excellent yields and ee values at the same time. Noteworthily, large scale preparation experiment was also demonstrated when amplified the reaction system to 10 g scale experiment, and products were obtained with high yields and ee values.
