An efficient methodology is described and exploited for the preparation of differently substituted indoles and azaindoles via microwave-assisted cycloisomerization in water of 2-alkynylanilines and alkynylpyridinamines, which is promoted by catalytic amounts of neutral or basic salts or by stoichiometric weak organic bases. Good to high yields in the cyclization can be achieved for a variety of 2-amino(hetero)aryl alkynes. Reactions are run without any added metal catalyst. A comparison with the cycloisomerization conducted under conventional heating is also described. An efficient methodology is described for the preparation of differently substituted 1H-indoles and 1H-azaindoles via microwave-assisted cycloisomerization in water of 2-alkynylanilines and alkynylpyridinamines, promoted by catalytic amounts of neutral or basic salts or by weak organic bases.

A novel synthetic approach toward benzo[a]carbazoles or 6-amino benzo[a]carbazoles containing an unprotected NH unit through Rh(iii)-catalyzed cascade reactions of 2-arylindoles or 2-arylindole-3-carbonitriles with alpha-diazo carbonyl compounds has been established. To our knowledge, this is the first example in which the NH unit of indole is used as a directing group for an intramolecular C(sp2)-H bond functionalization to give benzo[a]carbazole derivatives. Notably, this method features easily obtainable substrates, good functional group tolerance, excellent regio-selectivity, and high atom-efficiency.
