title: Synthesis of polysubstituted 5-aminooxazoles from alpha-diazocarbonyl esters and alpha-isocyanoacetamides.
abstract: A novel and efficient reaction for the synthesis of 2-keto-5-aminooxazoles is developed. The entire sequence is realized by simply heating a xylene solution of alpha-diazocarbonyl esters and alpha-isocyanoacetamides without any promoters. A possible mechanism for the entire sequence is proposed.
