The reaction of aldehydes with oxido ylides shows a dramatic dependence of alkene stereochemistry on the distance between oxygen and phosphorus atoms; ylides with proximal 0 and P atoms favor production of g alkenes. The high r stereoselectivity with r-oxido ylides is not mainly attributable to intr

## Abstract Wittig reagents (__1a–c__) react with N‐(phenylsulfonyl)‐1,4‐benzoquinone monoimine __2a__ to give adducts __3a__, __4a__, and __4b__. On the other hand, the reactions of __2b__ with the same ylides (__1a–c__) yield the new products __3b__, __6a__, and __6b__, respectively. Mechanisms a
