Methoxy-substituted 2-isopropenyl-2,3-dihydrobenzofurans were prepared from methoxy-substituted phenols and 1,4-dibromo-2-methyl-2-butene in one-step reactions. Their acylations with acetic acid–trifluoroacetic anhydride or N-methylformanilide–phosphoryl chloride were studied.
甲氧基取代的 2-异丙烯基-2,3-二氢苯并呋喃是由甲氧基取代的苯酚和 1,4-二溴-2-甲基-2-丁烯通过一步反应制备的。研究了它们与乙酸-三氟乙酸酐或 N-甲基甲酰基苯胺-磷酰氯的酰化反应。
