Novel diastereoselective photo-induced pinacolcouplingreactions of acetophenones by using triethylamine and chiral tertiary amines as electron donating co-sensitizers were studied. Various influence factors including solvents, substituents, and chiral amines on both the diastereoselectivity and yield were examined. The diastereoselectivities were enhanced in supramolecular systems of cyclodextrins

Induced by TiCl4-Al/CH2(COOEt)2 in CH2Cl2, some aromatic aldehydes and acetophenone can afford the corresponding 1,2-diols in 13-91 % yields with good dl-diastereoselectivities within 45-60 min at room temperature.
