- Versatile strategies for the solid phase synthesis of small heterocyclic scaffolds: [1,3,4]-Thiadiazoles and [1,3,4]-oxadiazoles
-
New robust protocols for the solid phase synthesis of 5-alkylthio-, 5-alkyl/aryl-, and 5-acylamino-2-alkylamino-[1,3,4]-thiadiazoles are described based on a common resin bound thiosemicarbazide. A protocol for the solid phase synthesis of 2-alkyl/aryl-amino-5-alkylamino-[1,3,4]-oxadiazoles from a resin bound semicarbazide is likewise reported. The protocols have been verified by the preparation of four small libraries that all gave products in good to excellent yields and purity.
