Abstract
A simple synthesis of 2-hydrazinylidene-3-hydroxy-4H-furo[3,2-c]pyran-4-ones is described. A mixture of (isocyanoimino)(triphenyl)phosphorane, an aromatic aldehyde, and dehydroacetic acid (=3-acetyl-2-hydroxy-6-methyl-4H-pyran-4-one) undergo a 1 : 1 : 1 addition reaction under mild conditions to afford the title compounds in excellent yields.
