Abstract
Lithium tetrafluoroborate (10 mol%) is found to catalyze efficiently the O---H insertion reactions of α-diazoketones with various alcohols including benzylic, allylic, propargylic and cyclopropyl carbinols to produce the corresponding α-alkoxy ketones in excellent yields with high selectivity. A solution of 10 mol% of LiBF4 in acetonitrile provides a convenient reaction medium to carry out the O---H insertion reactions under mild and neutral conditions.
