WebHerein, a mild Pd-catalyzed method for direct γ-C (sp 3 )-arylation of various unactivated β-alkoxy cyclohexenones is reported. The method is not only tolerated well with many ortho -hetero substituted aryl bromides but also with the sterically hindered ortho -dimethoxy or rigid ortho -diaryl aryl bromides. WebThe Stork enamine reaction and the intramolecular aldol reaction can be carried out in sequence to allow the synthesis of cyclohexenones. For example, reaction of the pyrrolidine enamine of cyclohexanone with 3-buten-2-one, followed by enamine hydrolysis and base treatment, yields the product indicated.
