An expedient, flexible and convergent access to selectively protected 1,5-dicarbonyl compounds. Applications to the synthesis of 2,6-disubstituted pyridines and thiopyridines

Intermolecular addition of 2-oxoalkyl radicals generated from the corresponding S-alkyl-O-ethyl dithiocarbonates on vinyl ketals afforded selectively protected 1,5-dicarbonyl compounds in good yields. These key-intermediates can be converted into a plethora of useful substances. Transformations to pyridines and thiopyridines were given as examples. Georg Thieme Verlag Stuttgart.

On the reduction of S-alkyl-thionocarbonates (xanthates) with phosphorus compounds

(Matrix presented) Reductive cleavage of the carbon-sulfur bond present in S-alkyl-thionocarbonates (xanthates) was achieved by high-yielding, tin-free radical reactions based on phosphorus reagents. The combination hypophosphorous acid/triethylamine/AIBN
