Synthesis of oxygen heterocycles
Ganguly,Mahata,Biswas
, p. 1347 - 1349 (2006)
A generalised scheme for the synthesis of flavones, flavonones and chromones involving 3-acyl-γ-pyrone intermediates has been developed. Convenient synthesis of other oxygen heterocycles using similar procedure have been outlined.
