promising method for the versatile synthesis of chiral 2-amino alcohols is provided by the enantioselective functionalization 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
通过简单杂环2-恶唑酮的烯烃部分的对映选择性官能化,涉及立体定义的易替换基团的引入,然后逐步取代,为手性2-氨基醇的通用合成提供了一种有前途的方法。这种方法的多功能性在不寻常的羟基氨基酸(例如他汀和羟基谷氨酸)的手性合成中得到了证明,它们是生物活性肽的关键成分。
