A stereocontrolled synthesis of a thioketal system that is a direct precursor of an active compound isolated from chanterelle was accomplished by using readily available methyl 11-[2-(2-oxoethyl)-1,3-dithian-2-yl]undec-9-ynoate as a key intermediate. The synthesis involves simple and straightforward reactions, such as addition of a lithiated alkyne to an aldehyde, alkyne hydrogenation using nickel boride, alcohol oxidation with Dess–Martin periodinane, and Z-to-E enone isomerization.
