aromatic lactams with carbonylcompounds in the presence of samarium(II) diiodide was found to undergo novel tandem desulfurization and reductive couplingreactions to generate α-hydroxyalkylated lactams in high yield. Stereochemistry of the coupling products was researched and the results that decreasing the steric bulkiness of the N-substituents as well as raising the reaction temperature leads to
