PREPARATION:A cyclohexadienecarboxylic acid derivative expressed by formula II is oxidized to give a 3,4-epoxy-1-cyclohexenecarboxylic acid derivative, which is then reduced and subsequently oxidized to provide a 1-cyclohexenecarboxylic acid derivative expressed by formula III. The resultant derivative expressed by formula III is then treated with a base to form a trianion, which is protected with a silylating agent and subjected to the Diels-Alder reaction with a compound expressed by formula IV to cleave the silyl group which is a protecting group. The resultant compound is further oxidized with air to afford the aimed compound expressed by formula V.
