The 1,3-dipolar cycloaddition of several substituted Münchnones with methyl α-cyanocinnamate and α-cyanocinnamonitrile leads to 2-pyrrolines which may be aromatized to pyrroles. This study shows the influence of steric factors on the regioselectivity of the reaction which is “a priori” difficult to predict.
用α-氰基肉桂酸甲酯和α-氰基肉桂腈甲基取代数个取代的慕尼黑酯的1,3-偶极环加成反应会生成2-吡咯啉,可将其芳香化为吡咯。这项研究表明,空间因素对反应的区域选择性的影响是“先验”很难预测的。
