## Abstract Cyclic ketene N,X‐acetals 1 are electron‐rich dipolarophiles that undergo 1,3‐dipolar cycloaddition reactions with organic azides 2 ranging from alkyl to strongly electron‐deficient azides, __e.g.__, picryl azide (2L; R^1^=2,4,6‐(NO~2~)~3~C~6~H~2~) and sulfonyl azides 2M–O (R^1^=XSO~2~;
