Reaction of CH acids with 2-arylidenecycloalkanones: Synthesis of ?-keto acid anilide derivatives of naphthalene, indene, fluorene, and phenanthrene
摘要:
2-Arylidene-cyclohexanone 1, -cyclopentanone 2, -1-indanone 3 and -1-tetralone 4 react with acetoacetanilide 5 yielding 2-oxo-4-aryl-3-carboxylic acid anilides derivatives of naphthalene 7, indene 8, fluorene 9 and phenanthrene 10. Reaction of 1 and 3 with benzoylacetanilide 6 yields the corresponding Michael adducts 11 and 12.
