Diastereoselective [4+3] Cycloadditions of Enantiopure Nitrogen-Stabilized Oxyallyl Cations

Diastereoselective [4+3] Cycloadditions of Enantiopure Nitrogen-Stabilized Oxyallyl Cations

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. (© Wiley‐VCH Verlag GmbH & Co.
