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.
