Synthesis of Polysubstituted 5-Aminooxazoles from α- Diazocarbonyl Esters and α-Isocyanoacetamides
摘要:
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.
