A number of 3-alkoxy-5-methyl-2-(α-methylcinnamoyl)-1,4-benzoquinones have been prepared by the reaction of 5-methyl-2-(α-methylcinnamoyl)-1,4-benzoquinone with alcohols. Irradiation of 3-methoxy-, 3-ethoxy-, and 3-isopropoxy-5-methyl-2-(α-methylcinnamoyl)-1,4-benzoquinones in solution gave 5H-pyrano[4,3,2-de][1,3]benzodioxins.
已通过将5-甲基-2-(α-甲基肉桂酰基)-1,4-苯醌与醇反应制备出多种3-烷氧基-5-甲基-2-(α-甲基肉桂酰基)-1,4-苯醌。在溶液中对3-甲氧基、3-乙氧基和3-异丙氧基-5-甲基-2-(α-甲基肉桂酰基)-1,4-苯醌进行辐照反应,得到了5H-
吡喃[4,3,2-de][1,3]苯二氧烃。
