Dithiin-containing systems

A peculiarity of the dithiin-containing systems (2, 12) lies in the opportunity to remove the sulfur bridge moiety in a highly stereoselective manner leading. [Pg.98]

The chemistry of the l,3-dithiole-2,4,5-trithione oligomer system 374 derived from monomers 375 and 376 (Scheme 49) has been the subject of a review <2006CHE423>. This system easily depolymerized (heat or UV irradiation at 253 nm) and was effective in Diels-Alder-type cycloadditions. Reactions with unsaturated compounds constituted an efficient method for synthesis of functionalized l,3-dithiole-2-thiones containing substituted 1,4-dithiin rings and are examples of reactivity of thione or sulfenyl substituents (stmctures 374-376) attached to the 1,3-dithiole ring carbon atom. [Pg.1003]

Thiarubrins. The light-sensitive, red T. A (CjjHgSj, Mr 228.33, oil) and B contain the anti-aromatic 1,2-dithiin system. They occur in various taxa of the Asteraceae and exhibit antibacterial, antifungal, nematicidic, and antiviral properties. Leaves of Aspilia africana con-... [Pg.647]
