enantiomers of 6,8-dioxabicyclo[3.2.1]octane and the alkyl substituted derivatives, exo- and endo-7-methyl, exo- and endo-5,7-dimethyl, 7,7-dimethyl, and exo- and endo-7-ethyl-5-methyl (exo- and endo-brevicomin), were synthesized stereoselectively with known configuration by standard synthetic methods, or with baker's yeast, or both. The correlation between the absoluteconfiguration of the bicyclic rings and
