A new phase-tag 1 which facilitates the parallel solution phase synthesis of carboxylic acids, esters, and carboxamides is reported. The new phase tag assists compound purification by enabling the selective resin capture of reaction products in either a reversible pH dependent manner (solid-phase extraction), or irreversibly in a Diels-Alder reaction.
据报道,新型相标签1促进了羧酸,酯和羧酰胺的平行溶液相合成。新的相标签通过以可逆的pH依赖方式(固相萃取)或在Diels-Alder反应中不可逆地选择性捕获反应产物,从而帮助化合物纯化。
