Organometallic Chemistry on Solid-phase. An overview

Solid-phase organic synthesis (SPOS) is the most important method for the production of combinatorial libraries and with the development of high-throughput screening, libraries are widespread in pharmaceutical and agricultural chemistry. Amongst all the synthetic transformations successfully applied to solid phase, the use of organometallic reagents for the formation of a new carbon-carbon bond has been scarcely pursued. In this overview we collected the most recent examples of the use of organometallic reagents of Li, Mg, Cu, Zn, Si and B for C-C bond formation. The use of organometallic reagents in Pd-catalysed cross-coupling reactions was not reviewed. Highly basic organometallics as organo-lithium and -magnesium reagents have been more largely employed than cuprates and zincates, suggesting that several kinds of resins can withstand relatively strong reaction conditions. © 2002 Published by Éditions scientifiques et médicales Elsevier SAS.
