The Diels-Alder reaction has been used to construct the diaryl ether unit in oxazolidine derivatives of β-[3-(aryloxy)aryl]-α-amino acids. Cycloaddition of acetylenic ketone 6 with substituted aryloxy dienes, and subsequent aromatization, provided the title compounds in good yields. Reaction of 6 with Danishefsky's diene furnished optically pure derivatives of L-tyrosine.
Diels-Alder反应已经用于在β-[3-(芳氧基)芳基]-α-氨基酸的恶唑烷衍生物中构建二芳基醚单元。炔基酮6与取代的芳氧基二烯的环加成反应,以及随后的芳构化,以高收率提供了标题化合物。6与Danishefsky's diene的反应提供了光学纯的L-酪氨酸衍生物。
