Straight to the point: An organocatalyzed, direct preparation of 3,4-disubstituted benzaldehydes from simple enals under mild conditions without the need for an additional oxidant has been developed. Notably, self-dimerization of an enal precursor and cro

Organocatalytic inter- and intramolecular [4+2] and [3+3] cycloadditions of α,β-unsaturated aldehydes to give polysubstituted aromatic aldehydes are described. High periselectivity for the cycloadditions, with catalyst effects exerted by l-proline and pyrrolidine-HOAc, as well as cocatalyst, additive effects, has been observed.
