Here, we report the first totalsynthesis of hinduchelins A-D, a family of nontoxic catechol derivatives from Streptoalloteichus hindustanus, possessing a druglike chemotype and modest iron-chelating ability. A concise synthesis was developed employing methyl 5-methyloxazole-4-carboxylate as a single starting material to provide hinduchelins A-D (and unnatural analogues) in only four steps and 5-15%
