The scope and limitations of dipolar cycloaddition reactions between nitrile oxides/nitrones and prop-1-ene-1,3-sultone have been investigated. A remarkably high degree of regioselectivity and stereoselectivity was observed. The homochiral sultam 8e was synthesized in a four-step reaction sequence s

## Abstract The readily available alkyl dicyanoacetates 1 reacted with the 1,3‐dipolar reagents arenecarbonitrile oxides 2β€² and arenecarbonitrile imines 5β€² to afford 1,2,4‐oxadiazol and 1,2,4‐triazol derivatives. The arenecarbonitrile oxides 2β€² with electron‐donating groups on the arene ring gave p
