Synthesis of functionalized triazoles is reported via Bi2WO6 nanoparticle (10 mol%) mediated 1,3-dipolar cycloaddition reactions of β-nitrostyrenes, phenylacetylene and chalcones with azides (80 °C, 2-6 h) in water. The regioselectiv

A simple and practical method for the regioselective preparation of β-enaminoketones is described. The method relies on the reaction of β-enaminoesters with organolithium reagents, and allows the preparation of a range of unusual β-enaminoketones.

Representative β-enaminones (1) and (2) react with N-alkyl-2-bromo-2-methylpropanamides (4a), (4b), and (4c) in the presence of NaH, to afford oxazolidin-4-ones (5) and (6) or spiro-oxazolidinone derivatives (7) and (8).The formation of an imidazolidin-4-one derivative (9) from 2-bromo-2-methylpropanilide (4c) is ascribed to the presence of an intermediate α-lactam (15).The behaviour of a spiro-oxazolidinone derivative on hydrolysis, reduction, and thiation is described.
