CHIRAL SYNTHONS FOR 2-AMINO ALCOHOLS - FACILE PREPARATION OF OPTICALLY-ACTIVE AMINO HYDROXY-ACIDS OF BIOLOGICAL INTEREST

A promising method for the versatile synthesis of chiral 2-amino alcohols is provided by the enantio-selective fuctionalization of the olefinic moiety of the simple heterocycle, 2-oxazolone, involving a stereodefined introduction of easily replaceable groups followed by stepwise substitution. Versatility of this method is shown in chiral synthesis of unusual hydroxy amino acids such as statine and hydroxyglutamic acid, which are the key components of bioactive peptides.
