By simple modification of the molar proportion of reactants, it was possible to selectively functionalize an aldehyde group in 2,5-furandicarbaldehyde (1), by Wittig reaction with stabilized ylides 2, The scope of the procedure is extended to the preparation of certain furancontaining natural fatty acid analogues.
通过简单地改变反应物的摩尔比例,就可以选择性地使
2,5-呋喃二甲醛(1)中的一个醛基与稳定的酰化物 2 发生维蒂希反应,从而使其官能化。
