Synthesis of 3,5-Disubstituted Isoxazoles and Isoxazolines in Deep Eutectic Solvents [PDF]
, 2015 The synthesis of different 3,5-disubstituted isoxazoles and related isoxazolines using choline chloride:urea as deep eutectic solvent (DES) in a one-pot three step reaction has been accomplished successfully. The use of highly nucleophilic functionalized

Stereoselective Intramolecular Azide 1,3-Dipolar Cycloaddition
HETEROCYCLES, 2003 Ethyl (E)-7-azido-6-[bis(tert-butoxycarbonyl)amino]-2-heptenoate undergoes a stereoselective intramolecular azide 1,3-dipolar cycloaddition leading to a stable triazoline. The configuration and the conformation of the triazoline obtained were determined by spectroscopic data and confirmed by molecular mechanics calculations.

A Novel Cycloaddition Reaction of Thermally Generated Sulfenes
CHIMIA, 1992 The highly strained ?-sultine 4, resulting from the addition of SO2 to benzobenzvalene, is shown to undergo a thermal cycloreversion which gives 1H-indene-1-thiocarbaldehyde dioxide (6) as an intermediate and subsequently 1H-indene-1 ...
