The present invention is directed to benzoquinazilinone compounds of formula (I) which are M1 receptor positive allosteric modulators and that are useful in the treatment of diseases in which the M1 receptor is involved, such as Alzheimer's disease, schizophrenia, pain or sleep disorders. The invention is also directed to pharmaceutical compositions comprising the compounds, and to the use of the compounds and compositions in the treatment of diseases mediated by the M1 receptor.

Rearrangement of spiro[5,2]octan-4-ol, 1, in acidified THF-H2O2 is a selective process in which substitution occurs with retention of configuration and ring-expansion with inversion of the carbinyl center.
螺[5,2] octan-4-ol,1在酸化的THF-H 2 O 2中的重排是一种选择性过程,其中取代发生且保留构型,而环扩展与羰基中心倒置。
