Synthesis of (+)-ribostamycin by catalytic, enantioselective hydroamination of benzene.

ABSTRACT: Aminoglycosides (AGs) represent a large group of pseudoglycoside natural products, in which several different sugar moieties are harnessed to an aminocyclitol core. AGs constitute a major class of antibiotics that target the prokaryotic ribosome of many problematic pathogens. Hundreds of AGs have been isolated to date, with 1,3-diaminocyclohexanetriol, known as 2-deoxystreptamine (2-DOS), being the most abundant aglycon core. However, owning to their diverse and complex architecture, all AG-based drugs are either natural substances or analogues prepared by late-stage modifications. Synthetic approaches to AGs are rare and lengthy; most studies involve semi-synthetic reunion of modified fragments. Here we report a bottom-up chemical synthesis of the 2-DOS-based AG antibiotic ribostamycin, w
