Syntheses in the Isocamphane Series XLII [1]. Synthesis and Odour of 5-exo-Hydroxycamphene (Isonojigiku Alcohol)

Abstract

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.
