摘要:
Toward the synthesis of FR225654, an antidiabetic natural product, the Sharpless asymmetric dihydroxylation of chiral bishomoallylic alcohols, never reported in the literature, was examined. Employing the pyrimidine class of ligands, a high level of matched diastereoselectivity was obtained. An application to the stereoselective synthesis of the C1-C10-C5 fragment of FR225654 was performed.
