Resolution and EPC synthesis of both enantiomers of 2,5-Dimethylbicyclo[3.2.0]heptan-endo-2-ol, Key Intermediate in the Synthesis of Grandisol.
摘要:
The pure enantiomers of 2,5-dimethylbicyclo[3.2.0]heptan-endo-2-ol, key intermediate in the synthesis of grandisol, have been conveniently prepared by optical resolution with (2S)-(-)-and (2R)-(+)-1-(4-toluenesulphonyl)pyrrolidine-2carboxylic acid chloride (NTP-Cl) as resolving agents, and by an EPC synthesis employing commercially available (3R)-(-)-and (3S)-(+)-linalool as chiral sources.
