1,3-Bis(arylsulfonyl)-benzimidazolones 1a-d were synthesized by reacting benzimidazolones with arenesulfonyl chlorides in the presence of NaOH. Mono(arylsulfonyl)-benzimidazolone derivatives 5a-c were prepared from benzimidazolone by protecting one of the Natoms with a tert-butoxycarbonyl group followed by arylsulfonylation and deprotection in acidic medium. The antidiabetic activity of three compounds 1a, 1c and 5a has been determined.
通过在NaOH存在下将苯并咪唑酮与芳基磺酰氯反应合成了1,3-双(芳基磺酰基)-苯并咪唑酮1a-d。通过保护一个Na原子与叔丁氧羰基团化合后进行芳基磺酰化和在酸性介质中去保护,制备了单(芳基磺酰基)-苯并咪唑酮衍生物5a-c。确定了三种化合物1a、1c和5a的抗糖尿病活性。
