Abstract: A regioselective and concomitant transfer of thiocyanate (-SCN) and aroyl/acyl (-COR) groups from aroyl/acyl isothiocyanates onto oxiranes was achieved, giving thiocyanato benzoates in 100% atom economy. In this biomimetic organocatalytic process, one part (-SCN) of… read more here.

Abstract: A regio-, diastereo-, and enantioselective [2 + 4] annulation reaction of cyclic 1-azadienes with γ-nitro ketones is reported. In the presence of a chiral tertiary amine, the annulation reaction proceeded smoothly to furnish polysubstituted cyclohexanes… read more here.
