A simple and mild catalytic arylation via C-Cl bond activation is described. The phenyl group containing a 2-trifluoromethyl group was introduced into the aromatic imine molecules through C,C-coupling reaction between chloroarenes and the organozinc reage

The alkaloids chelerythrine (8b) and decarine (7c) have been synthesized through a benzyne-mediated cyclization of N-(2-halobenzyl)-1-naphthylamines 4 with KNH2 in ammonia/ether.The 7-hydroxybenzophenanthridine structure 16a proposed for the alkaloid fagaridine is questioned on the basis of comparison with a model compound (16b) synthesized by benzyne cyclization.For the 8,9-oxygenated alkaloids like nitidine (8i), this cyclization proceeded poorly, but a dramatic improvement occurred when LDA/THF at -78 deg C was used instead of KNH2/NH3.
