The invention relates to a process for the optical resolution of a dibenzo[b,d]azepinone derivative of formula II,
wherein R
1
is hydrogen or halogen and R
2
is either C
1-4
-alkyl optionally substituted with C
3-7
-cycloalkyl or benzyl which is optionally substituted with C
1-4
-alkoxy, to obtain a (S)-7-amino-5H,7H-dibenzo[b,d]azepin-6-one of formula I,
wherein R
1
is as in the compound of formula II. The (S)-7-amino-5H,7H-dibenzo[b,d]azepin-6-one of formula I can be used as a chiral building block for the preparation of malonamide derivatives which have the potential to act as γ-secretase inhibitors and therefore may be useful in the treatment of Alzheimer's disease and cancer.
该发明涉及一种用于光学分辨二苯并[b,d]氮杂环己酮衍生物的过程,其化学式为II,其中R1为氢或卤素,R2为C1-4烷基,可选择性地取代为C3-7环烷基或苄基,苄基可选择性地取代为C1-4烷氧基,以获得化学式为I的(S)-7-氨基-5H,7H-二苯并[b,d]氮杂环己酮,其中R1如化合物II的情况。化学式为I的(S)-7-氨基-5H,7H-二苯并[b,d]氮杂环己酮可用作手性构建块,用于制备马隆酰胺衍生物,这些衍生物有潜力作为γ-分泌酶抑制剂,因此可能在治疗阿尔茨海默病和癌症方面有用。
