Enols of 1,1-Diformylacetone in the Synthesis of 5-Acylpyrimidines

Benneche,Tore,Undheim,Kjell

, p. 529 - 532 (2007/10/02)

The enol acetate of 3-oxobutanal has been formylated using ethyl orthoformate to provide the enol ether of 1,1-diformylacetone.The latter has been condensed with methylisothiourea to yield isomeric 5-acetyl and 4-methyl-5-formyl- pyrimidines, the ratio being dependent on the reaction conditions.
