Abstract A convenient synthesis of 1-oxo-1,2,3,4-tetra-hydrocarbazoles has been developed by reaction of 2-aminocyclohexanone hydrochlorides with various phenylhydrazine hydrochlorides viaFischerindolesynthesis under mild conditions. The method is more satisfactory in terms of the easy availability of starting materials and the simple one-pot operation.

shown to activate the CpxRA system by inhibiting the phosphatase activity of CpxA. Herein we report the initial structure-activityrelationships of this scaffold by focusing on three approaches 1) A-ring substitution, 2) B-ring deconstruction to provide N-arylated amino acid derivatives, and 3) C-ring elimination to give 2-ethylamino substituted indoles. These studies demonstrate that the A-ring is amenable
