Abstract
New C 2-symmetric chiral (4 S,4′ S)-bioxazoles 3a and 3b, possessing chirality on their backbone, were synthesized efficiently starting from L-tartaric acid. The structure of 3a was determined by X-ray crystal structure analysis. With these novel chiral bioxazole ligands, as a preliminary investigation for their effects on the enantioselectivity, rhodium(I)-catalyzed enantioselective hydrosilylations of acetophenone were carried out.
