α-aminobenzyl nitriles has been achieved by eco-friendly Strecker reactions using potassium hexacyanoferrate(II) as a cyanide source, benzoyl chloride as a promoter, and potassium hydroxide as a base. The protocol has the advantages of using a nontoxic, nonvolatile and inexpensive cyanating agent, employing a simple work-up procedure and producing high yields.
使用六氰基高铁酸钾 (II) 作为氰化物源,通过生态友好的 Strecker 反应实现了由 N-苄氧基羰基氨基和 N-甲苯磺基氨基-苄基苯砜原位生成的醛亚胺氰化为相应的 N-保护的 α-氨基苄基腈,苯甲酰氯作为促进剂,氢氧化钾作为碱。该协议的优点是使用无毒、非挥发性和廉价的氰化剂,采用简单的处理程序,产量高。
