Abstract
A diverse range of unsymmetrical tri- and tetrasubstituted cyclobutane structures can be produced in good yields and excellent diastereoselectivities using an efficient [2+2] heterodimerization of dissimilar acyclic enones upon visible light irradiation in the presence of a ruthenium(II) photocatalyst. The reaction is promoted by any visible light source.
