The Henry reaction of (1R)-(1,4:3,6-dianhydro-d-mannitol-2-yl)-1,4:3,6-dianhydro-d-fructose 5,5′-dinitrate. Different reactive features of nitromethane to nitroethane Original Research Article

Henry reactions of a novel higher sugar derivative, (1R)-(1,4:3,6-dianhydro-d-mannitol-2-yl)-1,4:3,6-dianhydro-d-fructose 5,5′-dinitrate (Alternate nomenclature: (1R)-(isomannid-2-yl)-1,4:3,6-dianhydro-d-fructose 5,5′-dinitrate), with nitromethane and nitroethane were studied. The kinetic and thermodynamic reactions with nitromethane under different conditions were carried out to afford (2S)- and (2R)-β-nitroalcohols, respectively. But when using nitroethane the reaction gave a (2S)-β-nitroalcohol with an inverted configuration at vicinal carbon C-1. Two stereogenic centers were generated, and one was altered in the reaction.
