New methodology for the solid-phase synthesis of benzothiazoles, benzimidazoles, and benzoxazoles has been developed by using a traceless 4-alkoxy-aniline linker. The desired products were released from the polymer support by imine-exchange process coupled with air oxidation. Combinatorial library consisting of 36 members has been synthesized using this linker. The yields are low to good, which highly
固相合成苯并噻唑,苯并咪唑和苯并恶唑的新方法已经通过使用无痕4-烷氧基-苯胺连接剂而开发出来。通过亚胺交换过程结合空气氧化将所需产物从聚合物载体上释放出来。使用此链接器合成了由36个成员组成的组合库。产量从低到高,这在很大程度上取决于构件。还研究了聚合物载体的再循环。
