β-Azole-containing α,β-unsaturated aldehydes were successfully reduced under highly enantioselective organocatalytictransferhydrogenation conditions. The products were obtained in good yields and up to 94% optical purity. This simple process was successfully applied to the synthesis of the C7−C14 fragment of ulapualide A, a natural product which exhibits promising antitumor activity.
