α-ACYL-SULFINES BY REACTION OF ACETYLENES WITH N-SULFINYL-AMIDES
Himbert, Gerhard,Pfeifer, Klaus-Peter,Finkele, Christoph E.
, p. 125 - 128 (2007/10/02)
Ynamines, ynethers and phenylacetylene react with N-sulfinyl-carboxamides to give 1,4,3-oxathiazines, which tend to devide by a retro Diels-Alder reaction into nitriles and 2-sulfinyl-amides, 2-sulfinyl-esters and sulfinylacetophenone, resp.
