Novel chiral 4,1-benzoxazepine-2,5-diones have been unusually synthesized in a single step by exploiting the chiral pool methodology. Substituted anthranilic acids afford N-acylanthranilic acids and (3R)-3-alkyl-4,1-benzoxazepines-2,5-dione upon coupling with α-chloroacids or α-bromoacids, respectively.
新型的手性4,1-苯并噁唑并吡啶-2,5-二酮通过利用手性合成库方法在单一步骤中异常合成。取代的氨基苯酸通过与α-氯酸或α-溴酸偶联,分别得到N-酰基氨基苯酸和(3R)-3-烷基-4,1-苯并噁唑并吡啶-2,5-二酮。
