We report here on the use of ethyl nitroacetate as a glycine template to produce α-amino esters. This started with a study of its condensation with various arylacetals to give ethyl 3-aryl-2-nitroacrylates followed by a reduction (NaBH4 and then zinc/HCl) into α-amino esters. The scope of this method was explored as well as an alternative with arylacylals instead. We also focused on various [2 + 3] cycloadditions, one leading to a spiroacetal, which led to the undesired ethyl 5-(benzamidomethyl)isoxazole-3-carboxylate. The addition of ethyl nitroacetate on a 5-methylene-4,5-dihydrooxazole using cerium(IV) ammonium nitrate was also explored and the synthesis of other oxazole-bearing α-amino esters was achieved using gold(I) chemistry.

Methods for the Stereoselective Cis Cyanohydroxylation and Carboxyhydroxylation of Olefins
Kozikowski, Alan P.,Adamczyk, Maciej
, p. 366 - 372 (2007/10/02)
Two valuable reagents for the cis-specific vicinal cyanohydroxylation and carboxyhydroxylation of olefins are described.The cyanohydroxylation process is based on the decarboxylative ring opening of 3-carboxyisoxazolines prepared by the cycloaddition reaction of carbethoxyformonitrile oxide with various alkenes.Fragmentation of the isoxazolines prepared from cis- and trans-2-butene has been found to occur without any crossover in stereochemistry.The carboxyhydroxylation process begins with the dipolar cycloaddition reaction of the nitrile oxide derived from thetetrahydropyranyl ether derivative of 2-nitroethanol.Deprotection, hydrogenation, and oxitative cleavage of the derived dihydroxy ketone yield the stereochemcally pure β-hydroxy carboxylic acid.
