The present invention is directed to spiropyrrolidine compounds of formula (I) which are inhibitors of the beta-secretase enzyme and that are useful in the treatment of diseases in which the beta-secretase enzyme is involved, such as Alzheimer's disease. The invention is also directed to pharmaceutical compositions comprising these compounds and the use of these compounds and compositions in the treatment of such diseases in which the beta-secretase enzyme is involved.

The synthesis of newpyrido[3′,2′:5,6]thiopyrano[3,2-b]indol-5(6H)-ones was accomplished by the Fischer-indole cyclization of some 2,3-dihydro-3-phenylhydrazonothiopyrano[2,3-b]pyridin-4(4H)-ones, obtained from the 2,3-dihydro-3-hydroxymethylenethiopyrano[2,3-b]pyridin-4(4H)-one, by the Japp-Klingemann reaction.

Derivatives 7–13 of a new tricyclicheteroaromaticsystem, pyrido[3′,2′:5,6]thiopyrano[4,3‐c]pyridazin‐3(2H,5H)‐one, were prepared as potential ligands at the benzodiazepinereceptor, in view of their structural analogy with potent ligands such as the pyrazoloquinolines of the CGS series II, and especially with the benzothiopyrano[4,3‐c]pyridazinones VI. They were obtained starting from the versatile

preparation of 2-substituted pyrido[3′,2′:5,6]thiopyrano[4,3-d]pyrimidines was accomplished from the intermediate 2,3-dihy-dro-3-dimethylaminomethylenethiopyrano[2,3-b]pyridin-4(4H)-ones by reaction with the appropriate binucleophile amidines. The antiproliferative activity of some new products was tested by an in vitro assay on human tumour cell lines (HL-60 and HeLa), but none of them showed any significant
