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
使用市售的(±)-α-硫辛酸作为固定化酮的新型化学上稳健的接头。通过分别通过Suzuki反应和Mitsunobu反应合成几种4-乙酰基联苯和4-烷氧基苯乙酮,证明了这种基于硫缩醛的接头在固相合成中的实用性。通过用[双(三氟乙酰氧基)碘]苯处理,可以容易地从固体载体上裂解产物。
