Diastereoselective trapping of chiral enantiopure oxyallyl cations by common dienes is reported. Excellent diastereoselectivities were obtained and depending on which auxiliary was used cycloadditions proceeded through a chelated or non-chelated pathway.

Newly introduced enantiomerically pure [4 + 2]cycloadduct-based 2-oxazolidinones which are conformationally fixed by bicyclo[2.2.2] and [2.2.1] ring systems, serve well as excellent chiral auxiliaries in the Evans' asymmetric strategy.
