The 2-(7-indolyl)pyrrole 12 has been synthesised from 4,6-dimethoxy-2,
3-diphenylindole 4 via the 1,4-diketone 11, generated from the 4-nitro
ketone 7. Reaction of tosylmethylisocyanide with some alpha,beta-unsat
urated ketones also yielded the indolylpyrrole 15 and the indolylpyrro
lylketones 13 and 17. (C) 1997 Elsevier Science Ltd.
