摘要

Commercially available (±)-α-lipoic acid was employed as a novel, chemically robust linker for the immobilization of ketones. The utility of this thioacetal based linker in solid-phase synthesis was demonstrated by synthesizing several 4-acetylbiphenyls and 4- alkoxyacetophenones via Suzuki and Mitsunobu reactions, respectively. The products were easily cleaved from solid support by treatment with [bis (trifluoroacetoxy) iodo] benzene.
