By exploiting the nucleophilicity of aroyl-S,N-ketene acetals, 23 diaroyl-S,N-ketene acetals can be accessed, although the aroylation leads to a significant bathochromic shift both in the solid and aggregated states as well as an increase in aggregate stability. Cyclized aroyl-S,N-ketene acetals can easily be converted into pyrazole systems in a one-pot synthesis.
通过利用芳酰基-S , N-烯酮缩醛的亲核性,可以得到23二芳酰基-S , N-烯酮缩醛,尽管芳酰化导致固态和聚集态的显着红移以及聚集体的增加稳定。环化芳酰基-S , N-烯酮缩醛可以在一锅合成中轻松转化为吡唑体系。
