(1R,5S)-9-methyl-9-azabicyclo[3.3.1]nonan-3-amine

This rigid, cationic scaffold is valuable for precise spatial orientation of functional groups, which is critical in receptor-binding and SAR optimization. (1R,5S)-9-methyl-9-azabicyclo[3.3.1]nonan-3-amine is a chiral bicyclic tertiary amine used as a synthetic intermediate in medicinal and pharmaceutical chemistry.It features a rigid azabicyclic [3.3.1] nonane framework with a bridgehead tertiary amine (N-methyl) and a primary amine at the 3-position, both locked into a well-defined (1R,5S) stereochemical configuration.
