Pyrido[3,4-c]Thiazoles through Combined Palladium-Catalysed Coupling of 2-Substituted-5-acetyl-4-thiazolyltriflates with Alkynes/Annulation Reactions

2-Substituted-5-acetyl-4-thiazolyltriflates give in good yields functionalised pyrido[3,4-c]thiazoles through combined palladium-catalysed coupling with 1-alkynes/6-endo-dig annulation reactions in the presence of ammonia.
