The nitro-Michaeladdition of organolithium species to 2-nitroglycal derivatives was investigated. This methodology affords straightforward and stereoselectiveaccess to C-nitroglycosides, which are excellent precursors to C–N-acetylglycosamines. The corresponding products bearing an aromatic, heteroaromatic, alkynyl, alkenyl, or alkyl moiety were isolated in good yields with excellent selectivities
