Iron-Catalyzed Enantioselective Intramolecular Inverse Electron-Demand Hetero Diels–Alder Reactions: An Access to Bicyclic Dihydropyran Derivatives
Résumé
A highly enantioselective iron-catalyzed Intramolecular Inverse Electron-Demand Hetero Diels-Alder (IIEDHDA) reaction is reported. By using a chiral semicorrin ligand in the presence of 2,6 lutidine, good isolated yields and excellent enantioselectivities were observed (up to 96% ee). Thanks to the versatile post-functionalization of the acyl-imidazole moiety, this methodology represents a unique example of the straightforward construction of highly valuable enantioenriched bicyclic dihydropyran derivatives.
