A Mannich-like zinc-mediated three-component reaction of aromatic halides, amines, and paraformaldehyde is described. This procedure, which involves the in situ formation of arylzinc reagents, allows the straightforward synthesis of a range of functionalized tertiary benzylamines.

Several functionalized diarylmethylpiperazines and 1,2-diarylethylpiperazines have been synthesized in moderate to high yield according to a one-step three-component coupling between an aromatic or a benzylic organozinc reagent, a piperazine derivative, and an aromatic aldehyde. The procedure can be extended to the synthesis of benzylpiperazine derivatives or beta-arylethylpiperazines toward the use of paraformaldehyde or aliphatic aldehydes. (C) 2007 Elsevier Ltd.
