Several π-excessive heteropolyaromatic compounds, which contain furan and thiophen ring and are possible antifungal agents, have been synthesized in good yields according to two general methods. The first method has been used to prepare compounds possessing thiophens linked by their 2- and 5-positions, such as the ter-aryls 2b, 2d and 2a. Two precursors of these compounds have been obtained either
根据两种常规方法,已经以良好的产率合成了几种含有呋喃和噻吩环并且可能是抗真菌剂的π-过量的杂多芳族化合物。第一种方法已用于制备具有通过其2位和5位连接的噻吩的化合物,例如叔芳基2b,2d和2a。这些化合物的两种前体已通过Glaser反应或使用新型的Pd介导的反应获得。第二种方法由Ni或Pd催化杂芳烃卤化物通过杂芳格氏试剂或卤化锌交叉偶联的杂芳基化反应制得,包含两个杂芳族单元的双芳基1a-e,和三芳基2c。还已经通过选择性锂化从2-(2-噻吩基)呋喃(1c)开始制备化合物1e,然后进行溴化。
