METHODOLOGIES FOR THE SYNTHESIS OF β-CARBOLINES [PDF]
β-Carbolines are an important class of heterocyclic compounds that are widely distributed in nature, being found in several families of naturally occurring alkaloids. Due to their diverse biological activities, the synthesis of β-carbolines is of high importance.

Simultaneous determination of tetrahydro-β-carbolines and β-carbolines
Chromatographia, 1996Reversed-phase ion-pair HPLC with fluorimetric detectors connected in series was studied for the simultaneous determination of two tetrahydro-β-carbolines and two β-carbolines. After additon of internal standards the samples were reacted with fluorescamine, and then subjected to serial extractions to remove their precursor (tryptamine) from the ...

β-Carbolines as potential anticancer agents.
European journal of medicinal chemistry, 2021β-Carbolines are indole alkaloids having a tricyclic pyrido[3,4-b]indole ring in their structure. Since the isolation of first β-carboline from Peganum harmala in 1841, the isolation and synthesis of various β-carboline derivatives surged in the ...

Abstract Herein, we report a facile synthesis of 3,4-dihydro-β-carbolines and aromatic β-carbolines from tetrahydro-β-carbolines, mediated by N -bromosuccinimide in toluene at 0 °C to room temperature (rt), in good to moderate yields.
