  摘要：

  The diene, (ZZ)-[(8,11)-pentadecadienyl]salicylic acid, (or 2-hydroxy-6-[(ZZ)-pentadeca-8,11-dienyl]benzoic acid), has been synthesised by two routes. In the first, the key intermediate methyl or ethyl 2-hydroxy-6-(7-bromoheptyl)benzoate has been converted to methyl or ethyl 2-hydroxy-6-(10-hydroxydec-8-ynyl)benzoate and thence by reaction of the corresponding bromide with 1-pentynylmagnesium bromide to methyl or ethyl 2-hydroxy-6-(pentadeca-8,11-dienyl)benzoate. Selective reduction afforded methyl or ethyl 2-hydroxy-6-[(ZZ)-pentadeca-8,11-dienyl]benzoate. An attempt to employ the Grignard reagent from methyl 2-methoxy-6-(non-8-ynyl)benzoate and reaction with 1-bromohex-2-yne was ineffective because of a side reaction of the former with ethylmagnesium bromide to give a ketone. In the third approach ethyl 2-methoxy-6-methylbenzoate was alkylated with 1-iodotetradeca-7,10-diyne and the product selectively reduced as before to the O-methyl ether ethyl ester. A variety of C-14 intermediates has been prepared for the derivation of the 8(E), 11(E), 8(E), 11(Z) and 8(2), 11(E) stereoisomers by the alkylation procedure. A similar methodology of alkylation can be adopted for obtaining corresponding trienes in which some progress has been made commencing with the synthesis of the 8(2),11(2),14 compound.
