Abstract:

The thioacetalization of carbonyl compounds 2 by using 2-(1,3-dithian-2-ylidene)-3-oxobutanoic acid as 1,3-propanedithiol equivalent and ethanol as solvent was investigated. The results showed that the thioacetalization of various carbonyl compounds proceeded smoothly and rapidly and afforded the corresponding dithioacetals 3 in high yields. Moreover, the thioacetalization exhibited a high chemoselectivity between aldehyde and ketone.

Key words: 2-(1,3-Dithian-2-ylidene)-3-oxobutanoic acid; 1,3-Propanedithiol equivalent; Carbonyl compound; Thioacetalization; Chemoselectivity, 2-(1,3-Dithian-2-ylidene)-3-oxobutanoic acid, 1,3-Propanedithiol equivalent, Carbonyl compound, Thioacetalization, Chemoselectivity
