An iodine mediated aromatization leading to a one-pot synthesis of iodo-N-arylanilines and N-arylanilines is reported. This highly regioselective aliphatic-aromatic transformation can be performed with various combinations of 2-cyclohexenones and anilines. The presence of a directing group is crucial for achieving

An efficient approach to prepare para-aryl phenols has been developed by using a Pd-catalyzed tandem γ-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

Recently, Nicolaou and Baran independently synthesized optically active 4-substituted 2-cyclohexenones via an efficient LiOH-mediated intramolecular aldol condensation. Thus far, application of their cyclization approach has been limited to ketoaldehydes where the R-group is branched. It is demonstrated that the LiOH-mediated
