Syntheses of cis and trans Methyl 12-Oxo-9-Dodecenoates, Their Corresponding Acetals, and Methyl 12-Oxo-trans-10-Dodecenoate

Abstract For the synthesis of deuterated geometrically isomeric 9,12-octadecadienoates to be used in metabolic studies in humans,1 methyl 12-oxo-cis- and trans-9-dodecenoates were required as intermediates. In 1954, Gunstone2 oxidized
