A highlyenantioselectivesynthesis of (−)- 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 (−)-juglomycin A] and 98.5% [for (+)-juglomycin A]. The synthetic strategy features an efficient combination of the Dötz annulation reaction and asymmetricdihydroxylation as the keys steps

Two synthetic routes based on a Dotz benzannulation toward the enantioselective synthesis of naphthoquinone antibiotics (-)- and (+)-juglomycin A are described. The stereoinducing step is based on asymmetric dihydroxylation. The syntheses are completed in seven to eight steps from Fischer carbene 12. (C) 2011 Elsevier Ltd. All rights reserved.
