Multicomponent Synthesis of Pentyl-Sulfonyl Amidines via Diazoalkane

A series of pentyl-sulphonyl amidines was obtained using a multicomponent synthesis process. The rearrangement of unstable tosylazide-cyclopentanonenamine cycloadducts yielded a diazoalkane intermediate. This primary, unstable reaction product showed good reactivity with certain acid compounds in order to form the corresponding derivatives.
