摘要
The ruthenium-catalyzed Markovnikov addition of acetic or benzoic acid to the triple bond of (E)-3-methylpent-2-en-4-yn-1-ol followed by acylation of the alcohol group in the diene formed under the action of low-toxic derivatives of carbonic and formic acids opens up a simple route to dienylic carbonates and formates. Activation of these esters by catalytic amounts of palladium(0) complexes under conditions of nucleophilic allylic substitution or decarboxylation affords functional dienes.
