Catalytic asymmetric acetalization of carboxylic acids for access to chiral phthalidyl ester prodrugs

Phthalidyl esters, commonly used prodrug moieties, are mostly prepared as a racemate. Here, the authors report an N-heterocylcic carbene-catalysed enantioselective acetalization of carboxylic acids and dialdehydes to give phthalidyl esters in high yields with good enantioselectivity.
