Abstract
New C-2-symmetric chiral (4S,4'S)-bioxazoles 3a and 3b, possessing chi rality on their backbone, were synthesized efficiently starting from L -tartaric acid. The structure of 3a was determined by X-ray crystal st ructure analysis. With these novel chiral bioxazole ligands, as a prel iminary investigation for their effects on the enantioselectivity, rho dium(I)-catalyzed enantioselective hydrosilylations of acetophenone we re carried out.
