Heterocycles from Nitrile Oxides. Part V; 4-AminoΔ2-1,2,4-Oxadiazolines; Heterocycles
(The Japan Institute of Heterocyclic Chemistry Publication, 1989-08)nitrile, ketone and nitrogen.. Nitrile oxides undergo 1,3-dipolar cycloaddition with alkanone hydrazones to give 4-amino-1,2,4-oxadiazolines. Lead tetracetate oxidation of these compounds brings about smooth heteroring ... -

Ring Transformation of Heterocycles: Part 3. A Conversion of 4-Amino-Δ2-1,2,4-oxadiazolines into 2-Arylamino-1,3,4-thiadiazoles and Oxaanalogues
(Japan Institute of Heterocyclic Chemistry, 1994)4-4-amino-Δ2-1,2,4-oxadiazolines (1) are transformed into the corresponding 2-arylamino-1,3,4-oxadiazoles (5), or thiadiazoles (6) via reaction with phenylisocyanate or phenylisothiocyanate. Followed by brief treatment of ...
