Summary.
The synthesis of the title compound is described. Hydroxylation of the endocyclic double bond of 2-acetyl-3,3-dimethylnorborn-5-ene furnished a mixture of nojigiku alcohol and the title compound. A shorter route leads from 2,5-norbornadiene solely to the desired camphoraceous smelling new hydroxy derivative to which the name isonojigiku alcohol is assigned.
Zusammenfassung.
Die Synthese des bisher unbekannten 5-exo-Hydroxycamphens wird beschrieben. Hydroxylierung der Doppelbindung in 2-Acetyl-3,3-dimethylnorborn-5-en führt zu einem Gemisch der beiden isomeren Camphenalkohole Nojigikualkohol und der Titelverbindung. Ein kürzerer Syntheseweg, ausgehend von 2,5-Norbornadien, führt ausschließlich zur camphrig riechenden Titelverbindung, die mit Isonojigikualkohol bezeichnet wird.
