Synthesis of Fused Isoxazoles: A Comprehensive Review

Engineering Proceedings
Pharmaceutically important isoxazoles are within the wide range of heterocycles. The isoxazole ring, being five-membered, is also found in many bioactive natural products in addition to synthetic drugs.

Complexation between oleanolic and maslinic acids with native and modified cyclodextrins [PDF]

, 2018
Oleanolic (OA) and maslinic (MA) acids are two natural triterpenoids with a wide range of beneficial effects for human health. However, their low solubility and permeability make their application in the food or industry difficult. The complexation of OA

Isoxazolium N-ylides and 1-oxa-5-azahexa-1,3,5-trienes on the way from isoxazoles to 2H-1,3-oxazines

Beilstein Journal of Organic Chemistry, 2014
Theoretical and experimental studies of the reaction of isoxazoles with diazo compounds show that the formation of 2H-1,3-oxazines proceeds via the formation of (3Z)-1-oxa-5-azahexa-1,3,5-trienes which undergo a 6π-cyclization.

Direct Nucleophilic Difluoromethylation of Aromatic Isoxazoles Activated by Electron-Withdrawing Groups Using (Difluoromethyl)trimethylsilane

ScienceOpen Research, 2014
The activation of aromatic diaryl isoxazoles with strong electron-withdrawing groups, such as the nitro, triflyl and the phenylsulfonyl groups, at the 4-position has enabled the first regio- and diastereoselective difluoromethylation at the 5-position of

Oxetanes: Recent Advances in Synthesis, Reactivity and Medicinal Chemistry [PDF]

, 2016
The 4-membered oxetane ring has been increasingly exploited for its behaviors, i.e. influence on physicochemical properties as a stable motif in medicinal chemistry, and propensity to undergo ring opening reactions as a synthetic intermediate.
