Regio- et stereo-reactivite d'une lactone dissymetrique. Determination de structure par effets nucleaires overhauser et modelisation moleculaire.
摘要:
Lactone I is an important intermediate in the synthesis of compounds with therapeutic properties. In order to prepare new derivatives, reactivity of I has been studied. Cis and trans conformations of both 2,3-diphenyl-1-oxabicyclo [3,1,0] hexanes VIIIa and VIIIb were assigned by H-1 N.M.R spectroscopy using NOE DIFF experiments, and molecular modelling.
