Development of new linkers for the formation of aliphatic C-H bonds on polymeric supports
摘要:
Two polmyeric linkers, 8 and II, were prepared in high yields. Attachment of an alkyl group to these linkers was facile, and their cleavage from the MeO-PEG polymer support was accomplished by desulfurization using Raney nickel to yield the new carbon-hydrogen bond product 6. The protocol reponed herein allows efficient preparation of new polymeric linkers as well as their possible application to combinatorial libraries. (C) 1997 Published by Elsevier Science Ltd.

Alkyl group bearing polymer 10 was prepared by way of sulfide 8 and thiol 11 in high yields. Cleavage of the alkyl chain from the PEG polymer support was accomplished either by homolysis under radical conditions or by desulfurization using Raneynickel to yield the new carbon-hydrogen bond product 12. The methodology developed will allow a variety of molecular scaffolds to be readily manipulated on
