  The invention relates to compounds of formula wherein the substituents are as described in claim 1 . Compounds of formula I are modulators for amyloid beta and thus, they may be useful for the treatment or prevention of a disease associated with the deposition of β-amyloid in the brain, in particular Alzheimer's disease, and other diseases such as cerebral amyloid angiopathy, hereditary cerebral hemorrhage with amyloidosis, Dutch-type (HCHWA-D), multi-infarct dementia, dementia pugilistica and Down syndrome.

  该发明涉及以下式的化合物 其中取代基如权利要求中所述 。式I的化合物是淀粉样蛋白β的调节剂，因此它们可能对治疗或预防与大脑中β-淀粉样蛋白沉积相关的疾病有用，特别是阿尔茨海默病，以及其他疾病，如脑淀粉样血管病变，遗传性脑出血伴淀粉样变性，荷兰型（HCHWA-D），多梗死性痴呆，拳击性痴呆和唐氏综合征。
