    摘要: The invention relates to a method for producing 1,3-dioxolane-2-ones of general formula (3) in basic reaction conditions by reesterifying the respective ester of general formula (1) in which R1 to R5 have the meanings indicated in the claims and the description. The invention further relates to a method for producing 2-hydroxy carboxylic acid esters of general formula (5) with or without isolation of the intermediate in the form of a derivative of the 1,3-dioxolane-2-one of general formula (3) in basic reaction conditions by reesterifying the respective ester of general formula (1) in which R1, R2, and R6 have the meanings indicated in the claims and the description. The method according to the invention allows the reaction to take place in very gentle basic conditions, causing fewer secondary reactions and providing a greater yield than reactions in highly polar aprotic solvents. Acid-sensitive and/or temperature-sensitive compounds can be synthesized.
