We have developed an efficient and convenient strategy for the regioselective synthesis of new conformationally restricted butyrophenones of the quinoline series. The 7-aminomethyl-7,8-dihydro-6H-quinolin-5-ones 9 were obtained from protected alcohol 5 via the tosylate, and also in a one-pot reaction via bromo derivative 6, with moderate-to-good overall yields in both cases.

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.
