Two formaltotalsyntheses of the (−)-salicylihalamides, based on chiral pool approaches, are reported. d-Glucose and l-rhamnose were used to prepare advanced intermediates 23 and 54, which can be converted in three or four steps, respectively, to the target compounds. The synthesis of 23 from a known d-glucose-derivative was accomplished in 12 steps and 17% overall yield, and the synthesis of 54 from
