The invention relates to benzoxazepinone derivatives of formula (I) wherein R1 is hydrogen, lower alkoxy, halogen or -NR'R'; n is 1 or 2; R',R' are independently from each other hydrogen or lower alkyl; R2 is hydrogen, lower alkyl, -(CH2)m-cycloalkyl, -(CH2)m-phenyl or -(CH2)m-O-lower alkyl; m is 0,1or 2; R3 is lower alkyl, -(CH2)m-C(O)O-lower alkyl, cycloalkyl or -(CH2)m-phenyl, which is unsusbtituted or substituted by one or two substituents, selected from the group consisting of halogen or lower alkyl; R4 is -(CH2)ο-phenyl, which is unsusbtituted or substituted by one or two substituents, selected from the group consisting of halogen, trifluoromethyl, -NR'R', nitro or _SO2NH2, or is - cycloalkyl, unsubstituted or substituted by phenyl, or is - (CR'R')ο-heterocyclyl, selected from the group defined in claim 1 and o is 1 or 2; and to pharmaceutically suitable acid addition salts thereof. These compounds are good Ϝ-secretase inhibitors for the treatment of Alzheimer's disease.
本发明涉及公式(I)的苯并
噁唑啉酮衍
生物,其中R1为氢、低碳氧基、卤素或-NR'R';n为1或2;R',R'各自独立地为氢或低碳基;R2为氢、低碳基、-(
