The synthesis of C-4 alkyl analogs of racemic (1 RS,4SR,5RS)-4-(4,8-dimethyl-5-hydroxy-7-nonenyl)-4-methyl-3,8-dioxabicyclo[3.2.1]octane-1-acetic acid and the corresponding (1RS,4RS,5RS)- derivative is described. The dioxabicyclo[3.2.1]octanes are useful as contragestational agents. The intermediate oxepane analogs are useful as intermediates in the preparation of the contragestational agent zoapatanol.
