presented to the receptor, at the active site, and the degree of conformational flexibility. The exo-1-azanorbornane 16a represents the optimum arrangement, and this compound is one of the most efficacious and potent muscarinic agonists known. In a series of isoquinuclidine based muscarinic agonists efficacy and affinity are influenced by the geometry between the cationic head.group and hydrogen bond acceptor
Diels–Alder adducts of 1,2-dihydropyridine with maleic and acrylic acid derivatives were stereospecifically converted by way of RuO4 oxidation into new 4-amino-1,2,3-cyclohexanetricarboxylic acids and 4-amino-1,3-cyclohexanedicarboxylic acids.
