A one-pot process for the transformation of relatively inexpensive serine derivatives into oxazine derivatives of γ-aryl-γ-hydroxy-α-amino acids is described. The reaction preferentially afforded 4,6-cis oxazines. The method can also be applied to the transformation of amino sugars into highly functionalized oxazines, which are precursors of chiral amines.
描述了将相对便宜的丝氨酸衍生物转化为 γ-芳基-γ-羟基-α-氨基酸的恶嗪衍生物的一锅法。该反应优先提供 4,6-顺式恶嗪。该方法还可用于将氨基糖转化为高度官能化的恶嗪,这是手性胺的前体。
