We report an improved method for the preparation of trichloromethylcarbinols from enolizable ketones. Trichloromethylcarbinols were obtained in good to excellent yields by using of a combination of CHCl3, n-BuLi, and chlorotitanium (IV) triisopropoxide. Hydrolysis of the trichloromethylcarbinol to an alpha,beta-unsaturated ester was also explored. (C) 2014 Elsevier Ltd. All rights reserved.
