Abstract Various aromatic and heteroaromatic compounds undergo smooth alkylation with cyclic allylic acetates in the presence of 10 mol% of indium trichloride under mild conditions to afford 3-substituted indoles, 2-substituted furan and pyrrole and cyclohexenyl-substituted arenes in good yields with high selectivity.
