A novel and facile synthesis of dienals and substituted 2H-pyrans via the Vilsmeier reaction of alpha-oxo-ketenedithioacetals

A novel and facile synthesis of dienals (3a, 3b) and substituted 2H-pyrans (4c, 4d) from a series of [small alpha]-oxo ketenedithioacetals containing a methyl group adjacent to the carbonyl group (1a-d)via the Vilsmeier reaction has been developed and a mechanism for the reactions has been proposed.
