The first Brønsted acid catalyzed asymmetric Mukaiyama aldol reaction of aldehydes using silylenolethers of ketones as nucleophiles has been reported. A variety of aldehydes and silylenolethers of ketones afforded the aldol products in excellent yields and good to excellent enantioselectivities. Mechanistic studies revealed that the actual catalyst may be changed from the silylated Brønsted acid
