A Rh(III)-catalyzed, regioselective C(2)—H activation/cyclization of N-methoxy-1H-indole-1-carboxamides and sulfoxonium ylides was developed. This novel synthetic procedure afforded dihydropyrimido[1,6-a]indol-1(2H)-ones in moderate to excellent yields. This reaction proceeds under simple and mild conditions with low catalyst loading and tolerates a wide range of substrates.

Key words: indoles, sulfoxonium ylides, cyclization
