✦ Synopsis
A highly enantioselective synthesis of (À)-and (+)-juglomycin A, a quinone antibiotic is described. The synthesis is completed in eight steps, and 19% overall yield and in a high enantioselectivity of 99.5% [for (À)-juglomycin A] and 98.5% [for (+)-juglomycin A]. The synthetic strategy features an efficient combination of the Do ¨tz annulation reaction and asymmetric dihydroxylation as the keys steps.
