Amination of pyrido[3,2,1-jk]carbazol-6-ones

Animation of 4-hydroxypyridocarbazolones 1 with aniline or benzylamine gave in good yields 4-amines 3. With piperidine in a sealed tube from 4-hydroxy- or 4-chloro-5-alkylpyridocarbazolones 1 or 4 ring opened 1-acylcarbazoles 5 were obtained. Only 4-hydro

Synthesis of Indoles and Isoquinolones from Phenylmalonate Heterocycles

A new synthesis of the indole system has been achieved by cyclodehydrogenation of amino phenylmalonate heterocycles.Thus, the 4-amino coumarins 1a,b or the 4-amino-2-quinolones 1c-g are converted to the indoles 2 with palladium on charcoal in boiling diph
