Localization of double and triple bonds in linear conjugated enyne-acetates and alcohols can be achieved in microgram scale through a two-step reaction sequence: epoxidation followed by catalytic hydrogenation or deuteration. This derivatization yields a saturated secondary alcohol of RCHOH(CH2),0R'
Various catalytic mhlbltors were investigated and lsoqumohne was found to be most selective m preventing "overhydrogenation" of terminal triple bonds in the presence of Lmdlar catalyst Methyl octadeca-12,17-dlynoate was prepared and selectwely partial hydrogenated (+90%) to the corresponding cts-dle
