Several examples of Sc(OTf)3-catalyzed aldol reactions of silyl enolates with aldehydes were been examined. Silyl enolates derived from ketones, thioesters, and esters reacted smoothly with different types of aldehyde in the presence of 5 mol % Sc(OTf)3 to afford the aldol adducts in high yields. Sc(OTf)3 was also found to be an effective catalyst in aldol-type reactions of silyl enolates with acetals. The reactions proceeded smoothly at -78 °C or room temperature to give the corresponding aldol-typc adducts in high )delds without side-reaction products. It should be noted that aldehydes were more reactive than acetals. For example, while 3-phenylpropionalde-hyde reacted with the ketene silyl acetal of methyl isobutyrate at -78 °C to give the aldol adduct in 80 % yield, no aldol-type adduct was obtained at -78 °C in the reaction of the same ketene silyl acetal with 3-phenylpropionaldehyde dimethyl acetal. The acetal reacted with the ketene silyl acetal at 0 °C to room temperature to give the... [Pg.884]

Sc(OTf)3 also catalyzes aldol-type reactions of silyl enolates with acetals. For example, the reaction of 3-phenylpropionaldehyde dimethyl acetal with the ketene silyl acetal of methyl isobutyrate proceeds at 0°C to room temperature to give the desired adduct in 97% yield (eq 2) ... [Pg.388]

It has been reported that the geometry of olefins obtained from the reaction of dialkyl l-(ethoxycarbonyl)ethylphosphonates and a-phenylpropionaldehyde can be controlled by choice of the phosphonate ester alkyl groups diisopropyl ester gives (E), while dimethyl ester gives (Z). This has now been confirmed for the... [Pg.322]
