把β-月桂烯与马来酸酐的分子间Diels-Alder环加成反应获得的环加成产物4-(4-甲基-3-戊烯基)-4-环己烯-1,2-酸酐(1)在乙酸乙酯溶剂中,用5%Pd/C为催化剂进行催化加氢,获得了一个新的化合物4-(4-甲基戊基)-环己烷-1,2-酸酐(2),然后,对2进行加水分解得到了另一个新化合物4-(4-甲基戊基)-环己烷-1,2-二羧酸(3)。用1HNMR(1H-1HCosy)和13CNMR(DEPT,HMQC,HMBC,INADEQUATE)等新的核磁共振测定手法对化合物1,2和3的结构进行了详细的解析及化学位移的归属。 The cycloaddition of 4- (4-methyl-3-pentenyl) -4-cyclohexene-1,2-dione obtained by cycloaddition reaction between β-myrcene and maleic anhydride by Diels- Anhydride (1) was catalytically hydrogenated with 5% Pd / C in ethyl acetate solvent to give a new compound 4- (4-methylpentyl) -cyclohexane-1,2-anhydride (2), and then hydrolyzing 2 to give a new compound 4- (4-methylpentyl) -cyclohexane-1,2-dicarboxylic acid (3). The structures of compounds 1, 2 and 3 were analyzed in detail and the chemical shifts were assigned by 1HNMR (1H-1HCosy) and 13CNMR (DEPT, HMQC, HMBC, INADEQUATE)
