O-(Silacyclobutyl)ketene acetals derived from esters, thiol esters, and amides reacted with a variety of aldehydes at room temperature without the need for catalysts. The O,O-ketene acetal of E-configuration reacted rapidly to afford the syn aldol products with high diastereoselectivity (93/7-99/1).
