To obtain stable derivatives of α-unsubstituted pyrroles, the reaction of the test pyrrole 9 with a series of chalcones 14a–h were studied. Michael adducts 16b–h could be isolated. In order to synthesize coloured derivatives, the reaction of different pyrroles 9, 21, 23, and 25 with diphenylpropynone 19 was investigated. In these cases, too, Michael-addition products were formed. The intense absorption
为了获得稳定的α-未取代吡咯衍生物,研究了吡咯9与一系列查耳酮14a – h的反应。迈克尔加合物16b – h可以隔离。为了合成有色衍生物,不同吡咯的反应9,21,23,和25与diphenylpropynone 19进行了研究。在这些情况下,也形成了迈克尔加成产物。400 nm附近的强吸收带使这些衍生物的鉴定变得容易。
