The preparation of (1R,4R)-bicyclo[2,2,1]heptane-2,5-dione from norbornadiene with >99% ee is described. This compound was used to make the synthetically useful (1R,2R,4R,5R)-exo,exo-2,5-diphenylbicyclo[2,2,1]heptane-endo,endo-2,5-diol and (1R,2R,4R,5R)-endo,endo-bicyclo[2,2,1]heptane-2,5-diol, which may prove to be valuable building blocks for novel ligand synthesis.
描述了从降冰片二烯制备(1R,4R)-双环[2,2,1]庚烷-2,5-二酮,ee > 99%。该化合物用于制备合成上有用的 (1R,2R,4R,5R)-exo,exo-2,5-二苯基双环[2,2,1]庚烷-endo,endo-2,5-二醇和 (1R, 2R,4R,5R)-endo,endo-双环[2,2,1]庚烷-2,5-二醇,这可能被证明是新型配体合成的有价值的构建模块。
