A silver-catalyzed cascade cyclization reaction of isocyanides with sulfoxonium ylides has been developed for the first time. This reaction provides a new and efficient method for the construction of highly functionalized 3-aminofurans and 4-aminoquinolines from readily available starting materials in a single step.

2,4,6-Triphenylpyrylium salts react with unsubstituted amidrazones to give dihydropyrazolo(1,5-c)pyrimidines or salts of pyridine imidoyl-N-imides.Pyridine imidoyl-N-imides are conveniently prepared from N-aminopyridinium and imidoyl chlorides.
