That 1,4-addition reactions of Grignard agent made from 1-bromo-3-triphenylmethoxyl-1-octene and organozinc agent made from 1-iodo-3-trimethysiloxy-1-octene with 2-(6-methoxylcarbonylhexyl)-4-(2- tetrahydro-pyranyloxy)-2-cyclopentenone both gave prostaglandin 〓 methyl ester statethat prostaglandin E compounds can be prepared by 1,4-addition reaction oforganozinc agent.

最后，研究了溴化-3-三苯甲氧基-1-辛烯基镁和碘化-3-三甲硅氧基-1-辛烯基锌与2-(6-甲氧羰己基)-4-(2-四氢吡喃氧基)-2-环戊烯酮通过1，4-加成反应合成〓甲酯的方法，结果表明，用有机锌试剂通过1，4-加成反应来合成PGE类化合物是可行的。

And 27.87%, 41.54%, 14.43% in the total volatile compounds of the abdominal and dorsal muscle. Sciaenops ocellatus has the fishy, specific grassy, fatty and melon-like odor. Hexanal and1-Penten-3-ol contribute to the form of fishy smell most greatly, also the environment and the cooperative or accumulative effects of other volatile compounds have certain impacts. Compared withthe dorsal muscle, the abdominal muscle is fishier (F0.01). 1-Octen-3-ol, 4-Heptenal and benzaldehyde have close relations to the form of characteristic flavor.
