Inclusion complexes of EMPO derivatives with 2,6-di-O-methyl-β- cyclodextrin: Synthesis, NMR and EPR investigations for enhanced superoxide detection

The free radical trapping properties of eight 5-alkoxycarbonyl-5-methyl-1- pyrroline N-oxide (EMPO) type nitrones and those of 5,5-dimethyl-1-pyrroline N-oxide (DMPO) were evaluated for trapping of superoxide anion radicals in the presence of 2,6-di-O-methyl-β-cyclodextrin (DM-β-CD). 1H-NMR titrations were performed to determine both stoichiometries and binding constants for the diamagnetic nitrone-DM-β-CD equilibria. EPR titrations were then performed and analyzed using a two-dimensional EPR simulation program affording 1: 1 and 1: 2 stoichiometries for the nitroxide spin adducts with DM-β-CD and the associated binding constants after spin trapping. The nitroxide spin adducts associate more strongly with DM-β-CD than the nitrones. The ability of the nitrones to trap superoxide, the enhancement of the EPR signal intensity and the supramolecular protection by DM-β-CD against sodium l-ascorbate reduction were evaluated.

A Facile Synthesis of α-Amino Esters via Reduction of α-Nitro Esters Using Ammonium Formate as a Catalytic Hydrogen Transfer Agent

Various nitroesters 3 were selectively and rapidly reduced to their corresponding amino esters 4 in very good yield using anhydrous ammonium formate as a catalytic hydrogen transfer agent.

CARBON-CARBON BOND FORMATION BY MEANS OF SUBSTITUTION AND ADDITION REACTIONS INVOLVING THE POLYMER-SUPPORTED CARBANION FROM METHYL NITROACETATE

A polymer-supported carbanion has been prepared from methyl nitroacetate and reacted with alkyl halides or activated olefins to give α-nitroesters.

α-Nitro Ketones and Esters from Acylimidazoles

The anion of 2-(2-nitroethyl)-1,3-dioxolane (4), prepared from the corresponding 2-bromo compound (3), undergoes condensation with acylimidazoles to give the 3-nitro-4-oxobutanal acetals (9), which can serve as valuable polyfunctional intermediates.Condensation with 1-(methoxyoxalyl)imidazole gives the tetrafunctionalized methyl 4-(1,3-dioxolan-2-yl)-3-nitro-2-oxobutanoate (13), which, however, decomposed on attempted deprotection of the ester function.The syntheses in excellent yields of simple α-nitro ketones and α-nitro esters from acylimidazoles and nitroethane and 2-nitropropane are also described.
