Positron emission tomography (PET), together with a suitable radioligand, is one of the more prominent methods for measuring changes in synaptic neurotransmitter concentrations in vivo. The radioligand of choice for such measurements on the cholinergic sy

We present here a practical stereoselective synthetic method to produce enantiopure isomers of a new muscarinic receptor antagonist, HL-031120 (3-quinuclidinyl-2′-cyclopentyl-2′-hydroxy-2′-phenylacetate, I). Four optical isomers were effectively by stereoselective synthesized using pivaldehyde as steric hindrance agent from the chiral starting material, ( S ) or ( R )-mandelic acid. The isomers were obtained with 70-76% yields in 98-99% e.e. Copyright Taylor & Francis Group, LLC.
