本文研究了氢型丝光沸石催化的月桂烯(1)二氢月桂烯(2)和异香茅烯(3)的甲氧基化反应。1的主产物是α-松油甲醚(13),其次是3,3-二甲基-1-甲氧亚基已烷(12),顺-1,8-二甲氧基对14)和反-1,8-二甲氧基对烷(16)。这与文献报道的产物有所不同,化合物12是在同类反应中未见报道的化合物。2的主产物是二氢月桂烯甲醚(17)。3的烷氧基化反应尚未见文献报道,其甲氧基化反应的主产物是异香茅烯甲醚(18)。这醚化产物的结构由元素分析,IR,~1H NMR和MS确定。
In this paper, the methoxylation of myrcene (1) dihydromyrcene (2) and isocaindene (3) catalyzed by hydrogen mordenite was studied. The main products of 1 are α-pinene methyl ether (13), followed by 3,3-dimethyl-1-methoxylidenehexane (12), cis-1,8- dimethoxylate 14) And trans-1,8-dimethoxy-paraffins (16). This is different from the products reported in the literature, and compound 12 is a compound that has not been reported in the same type of reaction. The main product of 2 is dihydromyrcenyl ether (17). 3 alkoxylation reaction has not been reported in the literature, the main product of its methoxylation is acesulfame methyl ether (18). The structure of this etherified product was confirmed by elemental analysis, IR, ~ 1H NMR and MS.
