## Abstract The oxoiminium salts 4a, b, and 8 obtained by alkylation with Et~3~OBF~4~ of the aldonitrones 3a, b, and 7 react with diphenyl hydrogen phosphite to give the __N__‐alkoxy α‐amino phosphonic esters 6 and 9a, b. Similarly, the cyclic imine oxides 10a, b and the cyclic oxime ethers 14a, b

## SR)-(-)-N-[1-(Triethoxymethyl)ethylidene]-p-toluenesulfinamide (2) was synthesized from the addition reaction of triethoxyacetonitrile with MeLi followed by (+)-(R)-d-menthyl p-toluenesulfinate (1R). Sulfinimine 2 underwent complete stereoselective reduction with 9-BBN and addition reaction wit
The synthesis of chiral, nonracemic, fully protected a,a-disubstituted a-amino acids via the Beckmann rearrangement of tosylated oximes 1 is described. The desired amino acids were obtained in good yields with excellent enantioseleetivities in relatively few steps.
