2-(2,5-Dimethoxyphenyl)pyrrole-3-carbonitrile
The Cadogan reaction of 2-aryl-3-nitropyridines leads to δ-carbolines. The title compound is a side product in this reaction, generated via a ring opening of a nitrene and cyclization. A crystal structure analysis gives an enormous unit cell.

The structure of β-carboline, also called norharman (systematic name: 9H-pyrido[3,4-b]indole), C(11)H(8)N(2), has been determined at 110 K. Norharman is prevalent in the environment and the human body and is of wide biological interest. The structure exhibits intermolecular N-H···N hydrogen bonding, which results in a one-dimensional herringbone motif.

An intramolecular inverse electron demand Diels–Alder approach to annulated α-carbolines
Intramolecular inverse electron demand cycloadditions of isatin-derived 1,2,4-triazines with acetylenic dienophiles tethered by amidations or transesterifications proceed in excellent yields to produce lactam- or lactone-fused α-carbolines.

Cytotoxic Bis-3,4-dihydro-β-carbolines and Bis-β-carbolines [PDF]
Ten bis-beta-carboline 1, 2 and bis-3,4-dihydro-beta-carboline 3, 4 derivatives, linked between carbons 1 and 1' by a polymethylene spacer, were synthesized from bistryptamine amides 9, 10. Some of them display a micromolar IC50 towards L-1210 cells.
