Starting with the development of new multicomponent reactions (MCR) in water, hydroxy thiazolidinethiones and oxazolidinones were prepared efficiently in a one-pot procedure. The reaction was carried out under mild conditions, consistent with the principles of “green chemistry”. These precursors were converted into different dienes containing terminal C–C double bonds by modifying the hydroxy group
Telomers of vinylenecarbonate with tetrachloromethane, which possess the 4-chloro-1, 3-dioxolan-2-one structure as a terminal ring, underwent smooth and selective conversion with primary aliphatic amines into 5-substituted 4-hydroxy-2-oxazolidones whose chemical reactions with the aid of acids, dehydration and phenylation, led to the corresponding 4-oxazolin-2-ones and 4-phenyl-2-oxazolidones, respectively. Treatment of 5-trichloromethyl-2-oxazolidinone with zinc-methanol resulted in the exclusive formation of 5-dichloromethyl-2-oxazolidone, in contrast to the corresponding 1, 3-dioxolan-2-one system which suffered complete reductive ring-opening even under milder conditions.
