2-[1,3]Dithian/dithiolan-2-ylidene-3-oxo-butanamide 2a/2b were synthesized and investigated in the thioacetalization reaction of aldehydes/ketones 3. The experiments revealed that 2a could be used as a nonthiolic, odorless 1,3-propanedithiol equivalent in the conversion of aldehydes/ketones into the corresponding dithianes 4, however, 2b was less effective. Moreover, the chemoselectivity of the thioacetalization of 3 in the presence of 2a is discussed.
