S-alkyl thiohydroximates from the results of Beckmann rearrangements on both geometricalisomers. The anti-(alkylthio)-isomers undergo fragmentation under Beckmann conditions. The syn-(alkylthio)-isomers may be converted to the anti-isomers by irradiation with u.v. light. Other evidence concerning the geometry of this series of compounds is discussed.
Disclosed are N-[(1R,4S,6R)-3-(2-pyridinylcarbonyl)-3-azabicyclo[4.1.0]hept-4-yl]methyl}-2-heteroarylamine derivatives and their use as pharmaceuticals.
cycloaddition of nitrile oxides to amidoximes is a general method for the sinthesis of 3,5-disubstituted 1,2,4-oxadiazole-4-oxides with the same or different substituents. The yields are only moderate since an equivalent amount of the nitrile oxide is consumed by reaction with the amine released in the fragmentation of the primary cycloadducts and reforms the amidoxime. With excess nitrile oxides the 1,2,4-oxadiazole-4-oxides
