Des 6H-thiazines-1,3 aux cephemes par cyclocondensation

The synthesis of new thiazines is described.Their structural determination and their spectroscopic parameters are examined.The cyclocondensation of these thiazines with ketenes is studied along with the reversibility of the reaction as a function of the nature of the substituents on position 4 and (or) 5 of 6H-1,3-thiazines.

The Preparation and Rearrangements of 5-acyl-2-phenyl-4-substituted 6H-1,3-Thiazines. X-Ray Molecular Structure of 3-Acetyl-2-ethoxycarbonyl-4-(3-oxobutylthio)-5-phenylpyrrole

5-Acyl-2-phenyl-4-substituted 6H-1,3-thiazines are prepared by the reaction of N',N'-substituted N2-thiobenzoylformamidines with methyl vinyl ketone or acrylaldehyde.Rearrangement catalysed by base and subsequent condensation with the acrylic reagent gives substituted pyrrolyl sulphides or substituted 2,6-dihydrothiopyranopyrrole.
