The cycloaddition reaction of benzothiazolium ylides with α-cyanocinnamamides: the synthesis of structural analogs of inhibitors of HIV-1 post-integrational repair
摘要
Benzothiazolium ylides generated in situ from benzothiazolium salts by the action of triethylamine reacted stereoselectively with α-cyanocinnamamides to form 1,2,3,3a-tetrahydropyrrolo[2,1-b][1,3]benzothiazoles in 15–91% yields. The resulting compounds were significantly more stable than their analogs derived from quinolinium ylides (KuINin), inhibitors of HIV-1 post-integrational repair.
