STEREOSELECTIVE TOTAL SYNTHESIS OF RACEMIC GRANDISOL via 3-OXIMINO-1,4,4-TRIMETHYLBICYCLOHEPTANE. AN IMPROVED PRACTICAL PROCEDURE.

Rosini, Goffredo,Geier, Monika,Marotta, Emanuela,Petrini, Marino,Ballini, Roberto

, p. 6027 - 6032 (2007/10/02)

(+/-)Grandisol was stereoselectively obtained via 1,4,4-trimethylbicycloheptane-3-one and its oxime by an improved procedure. 2,5,5-trimethylhept-1,6-dien-4-ol, the open chain molecule, was synthesized by two routes.Its conversion into (+/-)grandisol was performed emploing the photobicyclization as key step.
