Diastereoselective hydroboration of chiral enamines using an enantiomerically pure amine from an industrial waste material as the source of chirality
摘要:
By a hydroboration/oxidation procedure ti ans-aminoalcohols with dr values from 74:26 to greater than or equal to 95:5 were obtained. A bicyclic amine derived from the unnatural amino acid 2-azabicyclic[3.3.0]octane-3-carboxylic acid was used as the chiral precursor. The absolute configuration was clarified by X-ray structure of a descendant of the tr ans-aminoalcohols. (C) 2000 Elsevier Science Ltd. All rights reserved.
