A copper(ii)-mediated regioselective N-arylation of azoles has been developed using 8-aminoquinoline amide as a directing group. This reaction shows a broad substrate scope with different azoles such as pyrroles, indoles, pyrazoles and carbazole with good
Active manganese dioxide promoted cyclization of ortho-(1H-pyrrol-1-yl)aryl and heteroaryl carboxylic acids to 5H-pyrrolo[1,2-a][3,1]benzoxazin-5-one derivatives

The hitherto unknown lactone 5H-pyrrolo[1,2-a][3,1]benzoxazin-5-one and six of its substituted derivatives have been prepared by active manganese dioxide promoted oxidative cyclization of the corresponding 2-(1H-pyrrol-1-yl)benzoic acids, under mild conditions, in moderate yields. The method was successfully extended to the cyclization of some ortho-(1H-pyrrol-1-yl)heteroaryl carboxylic acids and 2-(1H-indol-1-yl)benzoic acids.
N-phenylpyrrole: A kinetic, though not thermodynamic preference for dilithiation
Faigl,Schlosser
, p. 10271 - 10278 (2007/10/02)
Under appropriate conditions the clean preparation of either the α-monolithiated or the o,α-dilithiated derivative of N-phenylpyrrole is possible. In the latter case, the first deprotonation occurs at the α-position. Dimetalation is kinetically but not thermodynamically favored.
