The use of tetrabutylammonium fluoride (TBAF) enables a versatile approach to
isoxazolines and pyrazolines by the cyclization of alkyne substrates under mild
reaction conditions. A deprotection/functionalization method is described,
leading to a substituted pyrazoline in good diastereoselectivity.

A Cu(I)-catalyzed three-component reaction of terminal alkynes,
trifluoromethyl diazo compounds, and nitrosoarenes provides a series of
trifluoromethyl-substituted dihydroisoxazoles in high yields under mild reaction
conditions.
