| Abstract: | RuH2(PPh3)4-catalyzed reductive cleavage reactions of chiral allylic cyclic carbonates with ammonium formate afforded optically active (E)-allylic alcohols with excellent regioselectivity. Alternatively, hydrogenolysis of propargylic cyclic carbonates in the presence of RuH2(PPh3)4 catalyst afforded allenic alcohols as a sole products. |
