Basicity of secondary penta-2,4-diynylamines and their reactions with phenyl isothiocyanate
Sipkina,Balova
, p. 1893 - 1899 (2003)
Secondary penta-2,4-diynylamines were synthesized, and their pK a(MeOH) values were obtained by means of nonaqueous potentiometric titration. The reactions of the amines with phenyl isothiocyanate, leading to 2-(phenylimino)-5-p(prop-2-ynilidene)thiazolidines, were studied. The N-butyl- and N-benzylthiazolidines with alkyl substituents at the triple bond, formed by the reactions, undergo autooxidation into thiazolidin-4-ones.
A general route to spirocycles by radical additions to exocyclic unsaturated sulphides and related compounds

Manganic acetate promoted additions of β-dicarbonyl compounds to unsaturated sulphides and enamine derivatives, which are readily available via iodocyclisation of unsaturated substrates, and subsequent elimination, afford spirocyclic systems.
