Use light instead of acids: Silylenolethers derived from aldehydes and ketones as well as aldehydes themselves react efficiently to give acetals in good to excellent yields. The substrate range with respect to both aldehydes and alcohols is broad, and acid- and hydrogen-labile protecting groups are tolerated.
