In 3-ethoxycarbonyl-2,4-dienal compounds, a thermal [1,5]-H shift of aldehyde hydrogen easily proceeded to produce the corresponding vinyl ketenes due to the remarkable substituent effect caused by the C3 ester group. The produced ketenes were captured by an alcohol and olefins to afford the corresponding esters and four-membered ring compounds, respectively.
在3-乙氧基羰基-2,4-二烯化合物中,由于C3酯基团引起的显着取代作用,醛氢的热[1,5] -H转移很容易进行以生成相应的乙烯基烯酮。生成的乙烯酮被醇和烯烃捕获,分别得到相应的酯和四元环化合物。
