摘要

Although dipotassiobenaoylacetone appeared to ionize the a-hydrogen of ethyl acetate, dilithio P-diketones underwent acylations with this and other aliphatic esters to form the corresponding 1, 3, 5-triketones. Certain of the triketones were prepared from two different combinations of pdiketones and esters. These products were converted by cyclizations to corresponding 2, 6-disubstituted 4-pyrones and 4-pyridones. These reactions, together ...
