α,β-Dehydroamino acid derivatives were synthesized in good yields from α-bromoketones or α-bromoesters and hydroxamates via a sequential procedure involving displacement of bromide by hydroxamate anion, followed by a base-induced elimination-isomerization reaction.
α,β-脱氢氨基酸衍生物是由 α-溴酮或 α-溴酯和异羟肟酸酯通过包括用异羟肟酸阴离子置换溴化物的顺序程序以良好的收率合成的,然后是碱诱导的消除异构化反应。
