Photoreaction of 1-cyano-2-phenylethene and 1,1-dicyano-2-phenylethene with β,β-dialkyl-substituted ketene silyl acetals in acetonitrile in the presence of aromatic hydrocarbon as a photosensitizer regioselectively afforded alkylated products in high yields.

Despite tremendous advances in enantioselective catalysis of the Diels-Alder reaction, the use of simple α,β-unsaturated esters, one of the most abundant and useful class of dienophiles, is still severely limited in scope due to their low reactivity. We report here a catalytic asymmetric Diels-Alder methodology for a large variety of α,β-unsaturated methyl esters and different dienes based on extremely reactive silylium imidodiphosphorimidate (IDPi) Lewis acids. Mechanistic insights from accurate domain-based local pair natural orbital coupled-cluster (DLPNO-CCSD(T)) calculations rationalize the catalyst control and stereochemical outcome.
First sequential Mukaiyama-Michael reaction/crossed-Claisen condensation using two molar ketene silyl acetals and one molar α,β-unsaturated esters promoted by a NaOH catalyst

supporting information; experimental part, p. 5930 - 5932 (2010/10/21)
The NaOH-catalyzed first sequential Mukaiyama-Michael reaction/crossed- Claisen condensation is developed using two molar ketene silyl acetals and one molar α,β-unsaturated esters in either a stepwise or one-pot manner.
