A series of dihydropyridines were identified that have an effect on the accumulation of tau, an important target in Alzheimer's disease. The dihydropyridine collection was expanded using the Hantzsch multicomponent reaction to develop preliminary structure–activity relationships.

The four-component Hantzsch reaction provides access to pharmaceutically important dihydropyridines. To expand the utility of this method, we have developed a route under organocatalytic conditions with good yields and excellent ee’s. Through catalyst screening, we found that a BINOL−phosphoric acid allowed enantioselectivesynthesis of six-membered heterocycles with a variety of substitution patterns
