Easy access to β-halo amino esters and aziridine 2-carboxylic esters from halohydrins
摘要:
The halohydrins prepared from epoxide esters, were treated with hydroxylamine derivatives. In subsequent reaction with NaOH/K2CO3/Bu4NHSO4 the N-protected beta-halo alpha-aminoesters thus obtained were converted into N-hydroxy ariridine 2-carboxylic esters in good yields.
