RESUMO
An indium(III)-catalyzed intramolecular Friedel-Crafts annulation for the efficient synthesis of pyrrolo[3,2,1-ij]quinolin-4-ones is described. The products are formed in good to excellent yields (51-97%) with diastereoselectivities up to >99 : 1 dr.

RESUMO
An efficient Lewis acid-catalyzed cyclopropane ring-opening/Friedel-Crafts alkylation sequence of methyl 1-(1H-indole-carbonyl)-1-cyclopropanecarboxylates is reported. The protocol affords functionalized hydropyrido[1,2-a]indole-6(7H)-ones in up to 99% yield.
