Abstract
PURPOSE: To prepare various carboxylic acids such as β-keto-acid ester, acylacetic acid amide, malonic acid derivatives, etc., in high yield, by reacting Meldrum's acid derivatives with alcohols, phenols, mercaptans, or amines.
CONSTITUTION: Carboxylic acid derivatives of the formulas III, IV, V or VI (R3 is lower alkyl; R4 and R5 are lower alkyl, phenyl, substituted phenyl; X and Y are O or S.) are obtained by reacting the compounds of the formula I or II (R1,2 are lower alkyl) with alcohols, phenols, mercaptans or amines of the formula R5YH or R5NH2, at about 100°C for several min. to ten-odd min.
