A novel totalsynthesis of Mansouramycin B (1) was performed via 10 steps in 28% overall yield starting from the readily available and cheap salicylaldehyde. Two key steps of this totalsynthesis are noteworthy. The first one is base‐promoted one‐pot aerobic aromatization of N‐tosyltetrahydroisoquinoline 6, the second one is oxidation of 5‐hydroxy‐3‐methyl‐isoquinoline 8 with iodobenzene diacetate
