Organocatalyzed asymmetric synthesis of dihydrodibenzofurans based on a dienamine process. 
The first organocatalyzed asymmetric method for the synthesis of dihydrodibenzofurans based on a dienamine process has been developed.  This two-step protocol works with a broad range of substrates and delivers only the cis-diastereomer in good yield with up to 91% ee.  The enantioenriched products have been transformed to highly functionalized and partially hydrogenated dibenzofurans in excellent diastereoselectivities.
