The reaction of formic acid and acetic acid with 3-methyl-cis-bicyclonona-2,7-diene, 3-methyl- and 3,4-dimethyl-cis-bicyclonona-3,7-dienes, and 3-methyl-cis-bicyclonon-7-en-3-ol leads to the exclusive formation of esters of 1-methyl- or 1,9-dimethyl-exo-brexan-5-ol with yields of 80-90percent.The reaction can be used as a convenient preparative method for the synthesis of 5-substituted brexanes.
