M. North et G. Zagotto, ASYMMETRIC DESYMMETRISATION OF MESO-NORBORNENE ANHYDRIDES UTILIZING METHYL PROLINATE AS A CHIRAL REAGENT, Synlett, (6), 1995, pp. 639-640
The reaction between methyl S-prolinate and meso-norbornene derived an
hydrides was found to give amido-acids with excellent asymmetric induc
tion. This methodology provides an inexpensive route for the preparati
on of optically pure, polycyclic, highly functionalised starting mater
ials for natural and unnatural product synthesis on a large scale.
