摘要

Abstract 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.
