ABSTRACT A method has been worked out to synthetize hitherto unknown 5-(2-chloroalkyl) Meldrum's acids 4 starting from easily accessible 2-chlorocarboxylic acid chlorides 1 in a two-step reaction. Reactions of dihaloethane and Meldrum's acid in the presence of potassium carbonate and the usefulness of compounds 4 are also presented.
