Strecker reaction for the synthesis of α‐aminonitriles was developed. The milling of aldehydes, amines, and potassium cyanide in the presence of SiO2 gave the corresponding α‐aminonitriles in good to high yields. The high efficiency of the mechanochemical Strecker‐type multicomponent reaction allowed the one‐pot synthesis of tetrahydroisoquinolines after a subsequent internal N‐alkylation reaction.
开发了用于合成α-氨基腈的Strecker反应的机械化学形式。在SiO 2的存在下对醛,胺和氰化钾进行研磨,可以以高至高收率得到相应的α-氨基腈。机械化学的Strecker型多组分反应的高效率使得在随后的内部N烷基化反应后可以一锅合成四氢异喹啉。
