Michael brings the rings: An asymmetricintramolecular oxa‐Michael reaction involving iminium activation has been developed. This reaction provides enantioenriched 1,4‐dioxane derivatives with up to 99 % yield and 98 % ee. The method allows for concise and stereoselective access to stereodiverse, complex tetracyclic compounds containing a bicyclo[2.2.2]octan‐2‐one backbone with multiple chiral centers

Desymmetrization of cyclohexadienones via enantioselective oxo-Michael reaction catalyzed by chiral phosphoric acid to afford highly enantioenriched 1,4-dioxane and tetrahydrofuran derivatives in excellent yields has been realized. The newly established methodology allows the facile enantioselective synthesis of cleroindicins C, D, and F.
An Alternative Approach to <i>para</i>-C–H Arylation of Phenol: Palladium-Catalyzed Tandem γ-Arylation/Aromatization of 2-Cyclohexen-1-one Derivatives
An efficient approach to prepare para-aryl phenols has been developed by using a Pd-catalyzed tandem gamma-arylation/aromatization of 2-cyclohexen-1-one derivatives with aryl bromides. This approach provides various p-aryl phenols from the phenol surrogates, 2-cyclohexen-1-one derivatives, in a single reaction step on the basis of C-H arylation.
