A straightforward and efficient copper(i)/amino acid-catalyzed intramolecular Ullmann-type C-O coupling reaction has been developed. This protocol affords a facile methodology for the synthesis of a series of novel 2,4,5-substituted oxazoles from readily accessible N-acyl-2-bromo enamides under mild conditions.

The reaction of 5(4H)-oxazolones with tetraethyl methanediylbis(phosphonate) afforded new 1,1-bisphosphonate and 1,1-bisphosphonic acid derivatives. Moreover, 5(4H)-oxazolones reacted with Wittig reagents to give the corresponding heterocyclic products. Treatment of 5(4H)-oxazolones with trisdialkylaminophosphanes gave the corresponding N-(1-dialkylcarbamoyl)-2-phenylvinylbenzamides. Mechanisms accounting for the formation of the new products are discussed. The biological activity of the newly synthesized compounds was also examined.
