The development of a flexible, component-based synthetic route to the amino sugar fragment of the lincosamide antibiotics is described. This route hinges on the application and extension of nitroaldol chemistry to forge strategic bonds within complex amino sugar targets and employs a glycal epoxide as a versatile glycosyl donor for the installation of anomeric groups.

for the directed hydrogenation of nitrogen heterocycles is described in which hydrogen is delivered cis to a hydroxymethyl group by a rhodium catalyst with a simple phosphine ligand. The chemistry is applied to the synthesis of the hygric acid moiety of lincomycin and the pipecolic acid moiety of Argatroban. A series of control experiments indicate that the stereoselectivity is a result of a combination

Abstractmagnified imageNew thioglycosides and C(1)‐alkylated thioglycosides (S‐ulosides) of lincomycin were synthesized, and their antibiotic activities were determined. The S‐aryl and S‐arylalkyl analogues 11a–11i were obtained by S‐glycosylation of the sulfoxides 7 with arenethiols, or by S‐alkylation of the thiol 14 with alkyl bromides. Lincomycin derivatives 27, 32a, 32b, 38a, 38b, 44, and 47 were prepared via Henry reaction or Michael addition of the lincosamine‐derived 1‐deoxy‐1‐nitropyranoses 22. The S‐alkyl derivatives showed a similar activity and specificity as lincomycin. Lipophilic S‐uloside analogues were two‐ to fourfold less active than the parent antibiotic, whilst the hydrophilic analogues were inactive.
