The chemistry of enoxysilacyclobutanes: highly selective, uncatalyzed aldol additions
摘要:
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).

O(Silacyclobuty1) ketene acetals derived from esters, thiol esters, and amides underwent facile aldol addition with a variety of aldehydes at room temperature without the need for catalysts. The uncatalyzed aldol addition reaction of O(silacyclobuty1) ketene acetals displayed the following characteristics: (1) the rate of reaction was highly dependent on the spectator substituent on silicon and the
