One-pot multi-component synthesis of pyrimido[4,5-b]indoles in solvent-free condition

Pyrimido[4,5-b]indole derivatives 4 were synthesized from a one-pot three-component reaction of aryl aldehyde 1, oxindole 2 and urea/thiourea 3 in solvent-free condition using ytterbium(III) triflate as catalyst.

DIHYDROPYRROLO- AND DIHYDROPYRIMIDOINDOLES

Aromatic aldehydes react with indole-2-carboxylic acid azides under acid catalysis conditions to give the corresponding 3-(α-halobenzyl)indoles, which react with aliphatic and aromatic amines to give the corresponding aminobenzylindoles.The latter undergo
