Furans, thiazoles, fluorene or thiophene incorporated calix[4]pyrrole analogues were synthesized and characterized. The synthesis was achieved by utilization of various building blocks such as 7, 13, 14, 18 and 21. Acid catalyzed condensation of those building blocks with acetone or meso-disubstituted dipyrromethanes afforded desired macrocycles.
合成并表征了呋喃,噻唑,芴或噻吩并入的杯[4]吡咯类似物。合成通过各种建筑块,例如利用实现7,13,14,18和21。这些结构单元与丙酮或内消旋二取代的二吡咯甲烷的酸催化缩合得到所需的大环化合物。
