Earlier we have reported the effect of arecoline thiazolidinone and morpholino arecolinederivatives as muscarinicreceptor 1 agonists in Alzheimer’s presenile dementia models. To elucidate further our Structure–Activity Relationship (SAR) studies on the chemistry and muscarinicreceptor 1 binding efficacy, a series of novel carboxamide derivatives of 2-(1-methyl-1,2,5,6-tetrahydropyridin-3-yl)morpholine

A decarboxylative C(sp2)–C(sp3) cross-coupling reaction of α-oxy carboxylic acids using dual nickel/photoredoxcatalysis has been developed for the synthesis of complex morpholines and other saturated heterocycles, affording direct entry to scaffolds of interest in drug discovery. This chemistry can be applied to the coupling of an array of (hetero)arylhalides and α-heteroatom acids, providing C(sp2)–C(sp3)-coupled
