1,4-Dihydrobenzoic acids 1a-e are converted by a one-pot reaction to benzene- mono-, di- and tricarboxaldehydes under Vilsmeier reaction conditions in yields ranging from 6 to 65%. The same methodology also serves to give naphthalene-1,3-dicarboxaldehyde (2f) from 1,4-dihydro-1-naphthoic acid (1f) in 91% yield.
1,4-二氢苯甲酸1a-e在维尔斯迈尔反应条件下通过一步反应转化为苯单、双和三羧醛,得率范围为6%到65%。相同的方法也可以从1,4-二氢-1-
萘酸(1f)中获得
萘-1,3-二羧醛(2f),得率为91%。
