Aryl imidazolyl sulfones bearing pendant hemisuccinamido groups for conjugation to biopolymer transport systems were synthesized from sulfide precursors. The peroxide-effected oxidation at sulfur was invariably accompanied by some cleavage-oxidation of the carboxamido groups to nitro functionalities, a process which could be minimized by careful control of the reaction conditions.
由硫化物前体合成了带有半琥珀酰氨基侧基的芳基咪唑基砜,用于与生物聚合物的运输系统偶联。过氧化物影响的硫的氧化反应总是伴随着羧酰胺基团的裂解氧化为硝基官能团,该过程可以通过仔细控制反应条件而最小化。
