Abstract:	(1 $S$ ,5 $R$ )-(-)-Karahana ether (8,8-dimethyl-2-methylene-6-oxabi-cyclo 3.2.1]octane) and (1 $S$ ,5 $R$ )-(-)-karahana lactone (8,8-dimethyl-2-methylene-6-oxabicyclo 3.2.1]octan-7-one) were synthesized from ( $S$ )-3-hydroxy-2,2-dimethylcyclo-hexanone. The natural karahana lactone was shown to be almost racemic ( $ca$ . 1.3 % e.e.).
