The cis-disubstituted oxocaneslauthisan (1) and laurenan (2) have been prepared from the lactone precursors (9b) and (9a) respectively by a sequence in which the key steps were methylenation and stereoselective hydroboration of the resulting enol ethers (11b) and (11a).

A general method for the construction of medium ring ethers is described in which a 2-substituted cycloalkanone was subjected to a Baeyer–Villiger ring expansion to the lactone, Tebbe methylenation of which afforded the enol ether which was subjected to a hydroboration–oxidation sequence to afford the 2,n-disubstituted oxacycle (n= ring size). Application of this procedure has led to efficient syntheses
