Mechanochemical Strecker Reaction: Access to α-Aminonitriles and Tetrahydroisoquinolines under Ball-Milling Conditions
Hernández, José G.,Turberg, Mathias,Schiffers, Ingo,Bolm, Carsten
, p. 14513 - 14517 (2016)
A mechanochemical version of the Strecker reaction for the synthesis of α-aminonitriles was developed. The milling of aldehydes, amines, and potassium cyanide in the presence of SiO2gave 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.

Paragraph 1214-1217, (2015/12/05)
The present invention concerns benzodioxane-piperidine with general formula I: wherein notably: R1 represents one or more identical or different substituent(s) on the benzene ring, each independently representing a hydrogen or halogen atom, or a C1-4 alkyl group, or a C1-4 alkoxy group or a C1-4 hydroxyalkyl group or a C1-4 alkylcarbonyl or an alkoxycarbonyl group or an OH group or an SO2R group with R alkyl, or a CN group, or a CF3 group, or an OCF 3 group; n=1, 2 or 3;m=0 or 1, andR2 represents one or more identical or different substituent(s) on the oxazolidinone or morpholinone ring, each independently representing: a hydrogen atom, a C1-4 alkyl group, or a C1-4 alkoxy group, or a C1-4 hydroxyalkyl group, or an alkylcarbonyl group, or an alkoxycarbonyl group, or an alkoxyphenyl group.
Catalyst-free Strecker reaction in water: A simple and efficient protocol using acetone cyanohydrin as cyanide source
Galletti, Paola,Pori, Matteo,Giacomini, Daria
experimental part, p. 3896 - 3903 (2011/09/12)
A simple, convenient, and practical method for the synthesis of α-amino nitriles through a one-pot, three-component Strecker reaction of a carbonyl compound, amine, and acetone cyanohydrin in water has been developed. Reactions proceed very efficiently without any catalyst at room temperature with high chemoselectivity and give, in some cases, the expected α-amino nitrile pure after direct separation from water. The protocol is particularly efficient for both aliphatic and aromatic aldehydes, and cyclic ketones, in combination with primary and secondary amines. An unusual application of the Strecker reaction to 1,2-diamines to obtain 1,2-diamino nitriles, and to cyclic secondary amines is reported. Copyright
