The present invention is directed to dihydrobenzoquinazilinone 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.
A novel palladium-catalyzed inward isomerization and hydraminocarbonylation of unactivated alkenes for the synthesis of α-aryl carboxylic amides has been developed. The combination isomerization-responsible catalyst and hydrocarbonylation-responsible catalyst was found to be a highly effective strategy to render the reaction feasible. The reaction shows highly functional group compatibility and site-selectivity
