Optical Resolution, Stereoselective Synthesis, and Crystal Structure of 9α‐(3‐Azabicyclo[3,3,1]nonanyl)‐2′‐cyclopentyl‐2′‐hydroxy‐2′‐phenylacetate
摘要:
9 alpha-(3-Azabicyclo[3,3, 1] nonanyl)-2'-cyclopentyl-2'-hydroxy-2'-phenylacetate (1) was synthesized and its enantiomers were obtained by the optical resolution of racemates with the chiral host N-p-toluenesulfonylglutamic acid. Optical pure 1 was also effective diastereoselective synthesized using benzaldehye as steric hindrance agent from the chiral starting material, (S) or (R)-mandelic acid. The structure of the title compound was first elucidated by X-ray analysis.
