Abstract

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