[EN] HETEROCYCLIC INHIBITORS OF BETA - SECRETASE FOR THE TREATMENT OF NEURODEGENERATIVE DISEASES [FR] INHIBITEURS HÉTÉROCYCLIQUES DE LA BÊTA-SECRÉTASE POUR LE TRAITEMENT DE MALADIES NEURODÉGÉNÉRATIVES
Substituted γ-chromones are rapidly produced in high (>90%) yield by reaction of morpholino (or piperidino)-methylene malonyl urethanes with 2-hydroxybenzaldehydes in hot ethanol solution.
The invention provides novel tricyclic compounds of Formula I′ that inhibit β-secretase cleavage of APP and are useful as therapeutic agents for treating neurodegenerative diseases.
