An efficient synthesis of the moisture-sensitive compound, 4-ethoxycarbonyl-2-methyloxazol-5-one, has been achieved. This compound undergoes high-yielding arylation and vinylation at the 4-position with organolead triacetates to give compounds which in water are converted to α-aryl and α-vinyl N-acetylglycine ethyl esters. These α-substituted glycine derivatives may be kinetically resolved in very
