Enamines, prepared readily from various carbonyl compounds, react with acetals or trialkyl orthoformates in the presence of Lewis acids such as BF3.OEt2 to give corresponding β-alkoxy carbonyl compounds or α-dialkoxymethyl carbonyl compounds in good yields.The reaction of dienamines with acetals or trialkyl orthoformates also selectively gives corresponding β,χ-unsaturated α-(α-alkoxyalkyl) carbonyl compounds or β,χ-unsatureted α-dialkoxymethyl carbonyl compounds in good yields.
