Syntheses of N-Alkylated Carbazolones via Pd(OAc)2-Mediated Intramolecular Coupling of N-Substituted 3-(Arylamino)cyclohex-2-enones

Abstract A variety of functionalized N-alkylated carbazolones were prepared via N-alkylation of 3-(arylamino)cyclohex-2-enones followed by an intramolecular oxidative coupling mediated by Pd(OAc) 2 under an oxygen atmosphere. This approach adopts an inverted sequence, consisting of the conventional...

Description
Summary:Abstract A variety of functionalized N-alkylated carbazolones were prepared via N-alkylation of 3-(arylamino)cyclohex-2-enones followed by an intramolecular oxidative coupling mediated by Pd(OAc) 2 under an oxygen atmosphere. This approach adopts an inverted sequence, consisting of the conventional annulation and subsequent N-alkylation.
