Alkylation of α-isocyano acetamide (2) with alkyl halide in MeCN at 0 °C in the presence of cesium hydroxide afforded the mono-alkylated product 1 in good to excellent yield.
0 °C 时,在氢氧化铯存在下,在 MeCN 中用烷基卤化物对 δ- 异氰基乙酰胺(2)进行烷基化反应,得到了单烷基化产物 1,收率从良好到极好。

Selective formation of 2H-2-imidazolines and 2-substituted oxazoles by using a multicomponent reaction of amines, either aldehydes or ketones, and alpha-acidic isocyano amides or esters is described. By selecting the appropriate solvent, Ag(I) or Cu(I) catalyst, or by employing a weak Bronsted acid, the product formation can be fully controlled and directed quantitatively to the desired heterocyclic
