-acyliminoacetates and N- acyl-α-triphenylphosphoranylideneglycinates. Wittig reaction of the latter ylides with aromatic and aliphatic aldehydes or ketones enables a new easy entry to N -acyl-α,β-dehydro-α-amino acid esters.
Ñ 酰基-α-triphenylphosphonioglycinates时用三乙胺转化成相应的平衡混合物 Ñ -acyliminoacetates和 N- 酰基- α-triphenylphosphoranylideneglycinates。 后者的酰基化物与芳族和脂族醛或酮的 维蒂希 反应使得 N- 酰基-α,β-脱氢-α-氨基酸酯易于进入 。
