Stereoselective syntheses of heterocycles represent an important area of application of intramolecular 1,3‐dipolar cycloaddition. With the aid of model compounds (1), n = 1, 2, it is demonstrated that also carbonyl ylides such as (2) and (3) can undergo this type of reaction. Reaction of (3), n = 1, affords (4) while reaction of (2), n = 1, 2, leads to the trans ‐coupled compounds corresponding to (4) .
