Ethyl-4-(tri-n-butyltin)-3-methyl crotonate and ethyl 4-(tri-n-butyltin)-3-methoxycrotonate were condensed with benzaldehyde and cyclohexanone. The regio- and stereochemical profiles were determined in an effort to control the course of dienolate additions to carbonyl compounds under acid-catalyzed conditions.
