A catalyst-free [5 + 1] cycloaddition reaction between isocyanides and C,N-cyclic N′-acyl azomethineimines as the “isocyanophile” leading to novel heterocycles has been developed. These reactions proceeded quickly and cleanly to afford the corresponding imin-1,3,4-oxadiazin-6-one derivatives in high to excellent yields. A wide range of C,N-cyclic N′-acyl azomethineimines and isocyanides were applicable
A three-component reaction of C,N-cyclic N′-acyl azomethine imines, isocyanides, and azide compounds: effective synthesis of 1,5-disubstituted tetrazoles with tetrahydroisoquinoline skeletons
A multicomponent reaction of isocyanides and C,N-cyclic Nâ²-acyl azomethine imines in the presence of TMSCl and NaN3 leads to tetrazole derivatives. These reactions proceeded cleanly to afford the corresponding 1,5-disubstituted tetrazoles containing a tetrahydroisoquinoline skeleton in high to excellent yields.
