Phenols, single-step condensation

An alternative preparation of benzofurans was carried out via a microwave-assisted Mannich condensation of paraformaldehyde and a secondary amine followed by cyclization with an alkynyl phenol 185 mediated by alumina doped with Cul (Scheme 67). The reaction can be carried out in a single-step... [Pg.247]
