α-Isocyano-β-phenylpropionamide 1 is synthesized from the corresponding amino acid in excellent yield. The unique reactivity of this bifunctional compound is exploited for the development of novel multicomponent synthesis of 5-aminooxazole 6, pyrrolo[3,4-b]pyridin-5-one 10 and 4,5,6,7-tetrahydrofuro[2,3-c]pyridine 13.
δ-异氰基δ-苯基丙酰胺 1 是由相应的氨基酸合成的,收率极高。利用这种双官能化合物的独特反应性,开发出了新型多组分合成 5-氨基恶唑 6、吡咯并[3,4-b]吡啶-5-酮 10 和 4,5,6,7-四氢呋喃并[2,3-c]吡啶 13 的方法。
