Synthesis of 4-(Acylacetyl)-1-phenyl-2-pyrazolin-5-ones from 3-Acyl-2H-pyran-2,4(3H)-diones. Their Synthetic Applications to Functionalized 4-Oxopyranopyrazole Derivatives.

The phenylhydrazones of 3-acyl-2H-pyran-2,4(3H)-diones (2), in refluxing acetic acid, underwent rearrangement to 4-(acylacetyl)-1-phenyl-2-pyrazolin-5-ones (6), from which some functionalized 4-oxopyranopyrazole derivatives were synthesized.This fi
