Synthesis of (R,R) and (S,S) bicyclo[3.3.0]octane-2,6-dione interactions between non-conjugated chromophores
Résumé
Opticafiy pure bicyclo(3.3.0]oc~-Z,6-dione is easily obtained with a yield of 4% for each enantiomer
from 1,5-cyolooctadiene 5 steps, by resolution of the intermediate diol wth menthyloxyacetiacid. Its CD is
60 % larger than twice the CD of a coresponding monoketone dicatingi indicating interactions between non-conjugated
chromophores
