2,2‐Disubstituted 1,3‐Dithianes from β‐Dicarbonyl Compounds 1,3‐Dicarbonyl compounds 2 can be condensed with 1,3‐propanedithiol ( 1 ) to yield 2,2‐disubstituted 1,3‐dithianes 3 which are remarkably stable in contrast to analogous open‐chain thioacetals 6 . Compounds with alkoxycarbonyl functions are easily hydrolysed to the corresponding carboxylic acids 11 which by further esterification with alkanols 12 yield estermodified 1,3‐dithianes 3 . All new compounds are characterized by 13 C NMR spectroscopy.
