Two strategies for the synthesis of fungerin and its derivatives have been developed. An orthogonally protected key 4,5‐di(hydroxymethyl)imidazole intermediate gave fungerin analogues in five steps. Furthermore 5‐(2‐sulfonylethyl)‐4‐bromoimidazole gave several target imidazoles after two additional steps with complete regioselectivity.
已经开发了两种合成真菌素及其衍生物的策略。正交保护的关键4,5-二(羟甲基)咪唑中间体通过五个步骤提供了fungerin类似物。此外,在另外两个步骤后,5-(2-磺酰基乙基)-4-溴咪唑具有完全的区域选择性,从而生成了几种目标咪唑。
