Racemic endo-5-acetyl-1,2,3,4-tetrachloro-7,7-dimethoxynorborn-2-ene was stereoselectively reduced by sodium borohydride to give only the S,S or R,R diastereomers. The crystal structure of the product displays no unusual features.
Microwave-Assisted Solvent-Free Diels-Alder Reaction - A Fast and Simple Route to Various 5,6-Substituted Norbornenes and Polychlorinated Norbornenes
Diels-Alder reaction. This procedure proved very versatile, fast, and with an easy workup step, and therefore suitable even for large-scale synthesis. Diels-Alder reactions - bicyclic compounds - cycloadditions - norbornene - microwave - polychlorinated norbornanes
