During the course of work in benzopyrone synthesis by thermal condensation of 8-ketoesters with phenols(') it has been observed that a minor amount of a byproduct was produced which could only be derived from a thermal reaction of the 8-ketoesters. Therefore attempts were carried out to synthesize t
All the hydroxy-ketoesters la-k described are derived from the addition of acetoacetate dianion to the corresponding aldehydes, following [2].
