Recent Advances in the Synthesis of 2<i>H</i>-Pyrans

In this review, we discuss the nature of the different physicochemical factors affecting the valence isomerism between 2<i>H</i>-pyrans (2HPs) and 1-oxatrienes, and we describe the most versatile synthetic methods reported in recent literature to access to 2HPs, with the only exception o...
