A novel, one-pot procedure for the preparation of N-acryloyl-a-amino acids involves the steps of:
i) reacting a ketone, an ammonium salt, and a cyanide salt in water, optionally in the presence of ammonium hydroxide and a co-solvent, to form an aminonitrile;
ii) acryloylating the aminonitrile in aqueous media to afford an acrylamidonitrile; and
iii) hydrolyzing with aqueous acid the acrylamidonitrile to provide the N-acryloyl-a-amino acid.
一种制备 N-丙烯酰基-a-氨基酸的新型单锅程序包括以下步骤:i) 在水中(可选择在氢氧化铵和助溶剂存在的情况下)使酮、铵盐和氰盐反应生成氨基腈;ii) 在水介质中使氨基腈丙烯酰化,得到丙烯酰胺腈;iii) 用水性酸水解丙烯酰胺腈,得到 N-丙烯酰基-a-氨基酸。
