A general procedure for the reductive coupling of N-tosylhydrazones with amines in the presence of Cu(acac)2 and Cs2CO3 has been developed. The protocol is very effective and chemoselective with various primary and secondary aliphatic amines, aminoalcohols as well as azole derivatives to give α-branched amines in good yields.

The development of new ROMP-based oligomeric benzyl phosphates (OBPn) is reported for use as soluble, stable benzylating reagents. These oligomeric reagents are readily synthesized from commercially available materials and conveniently polymerized and purified in a one-pot process, affording bench-stable, pure white, free-flowing solids on multigram scale. Utilization in benzylation reactions with a variety of nucleophiles is reported.

We describe a practical and efficient route for synthesis of 2-aminomethyl-1,2,3,9-tetrahydro-4H-carbazol-4-ones using an effective Fisher indole methodology. The most active compounds, 4b (QF 2003B) and 4c (QF 2003B), with pKi (5-HT2A/D-2) ratio of 1.28 show an antipsychotic profile according to Meltzer's classification, (C) 1998 Elsevier Science Ltd.

Starting from 2,5-dimethoxybenzoic acid we described a practical and efficientroute for synthesis of 6-aminomethyl-4-oxotetrahydroindoles with good to acceptable overall yields of 50-30%.
