Abstract:
Novel and highly stereoselective route to E-(but-1-en-3-yne-1-sulfonyl)hetarenes by palladium catalyzed Sonogashira type coupling of unstable E-2-chlorovinylsulfonylbenzene and E-2-(2-chlorovinylsulfonyl)pyridine was presented. Usage of potassium phosphate as novel base in Sonogashira reaction was demonstrated. Unusual coupling products in the Sonogashira reaction of E-2-(2-chlorovinylsulfanyl)benzothiazole with different alkynes were obtained.| Authors: | Visnevska, Julija; Belyakov, Sergey; Abele, Edgars | |
