Stereoselective synthesis of the optical isomers of a new muscarinic receptor antagonist, HL-031120

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.
