trans-Hydroxylation of cyclopent-5-ene[d]isoxazolines [PDF]
, 2013 The title reaction has been studied as a variant of the cyclopentane ring functionalization of cyclopent-5-ene[d]isoxazolines as the key intermediates in total synthesis of azaand oxo prostaglandin analogues by nitrileoxides approach.

Anionic Domino C-O-Heterocyclization Approach for the Synthesis of 5-Vinyl Isoxazolines
, 2007 5-Vinyl isoxazolines were isolated in high yields through domino nucleophilic addition–anionic C–O-heterocyclization, when allyl organometallics derived from trans-1,4-dihalobutene were reacted with nitrile ...

Synthesis and Antimicrobial Studies of Some Novel Pyrazoline and Isoxazoline Derivatives
E-Journal of Chemistry, 2009 A new series of 1H-3-(4’-substituted phenyl)-5-(6’’-methoxy napthaline)-2-pyrazolines (4a-e) and 1H-3-(4’-substituted phenyl)-5-(6’’-methoxynapthaline)-2-isoxazolines (5a-e) were synthesized by reacting 1-(4’-substituted phenyl)-3-(6’’-methoxynapthaline)-

A One-Pot Approach to Δ2‑Isoxazolines from Ketones and Arylacetylenes
, 2016 The sequential reaction of ketones with arylacetylenes and hydroxylamine in the presence of KOBut/DMSO followed by the treatment of the reaction mixture with H2O and KOH leads to Δ2-isoxazolines in up to 88 ...
