The condensation of resacetophenone with several α-substituted acetoacetates with anhydrous aluminium chloride as condensing agent has been investigated. Ethyl α-methyl-, α-ethyl-, α-benzyl-acetoacetates undergo the condensation with the formation of 5-hydroxy-6-acetyl-3-alkyl-coumarin derivatives. Negative results were obtained with ethyl α-prophyl-, α-allyl, α-chloro-acetoacetates, the original ketone being recovered. The results obtained have been discussed.
