The iron(III) chloride-catalyzed Friedel–Crafts arylation of 4-aryl-4-methoxy-2,5-cyclohexadienones, which were easily prepared by the phenyliodine(III) diacetate (PIDA)-mediated oxidation of 4-arylphenols in methanol, proceeded site-selectively to form meta-terphenyl (2,4-diarylphenol) derivatives in good yields. The subsequent PIDA-mediated oxidation and iron(III) chloride-catalyzed Friedel–Crafts arylation of the resulting products gave the corresponding 2,4,6-triarylphenol derivatives. The present method provides useful highly substituted polyarylated compounds. (Figure presented.).

Michael brings the rings: An asymmetric intramolecular 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. Copyright
