One-Pot Synthesis of 3-Substituted Isoxazoles from Phenyl Vinylic Selenide
Sheng, Shou-Ri,Liu, Xiao-Ling,Xu, Qu,Song, Cai-Sheng
, p. 2763 - 2764 (2007/10/03)
Phenyl vinylic selenide was adopted for 1,3-dipolar cycloaddition to nitrile oxides and subsequent oxidation-elimination furnished 3-substituted isoxazoles with good yields in a one-pot, two-step transformation.

, p. 685 - 702 (2007/10/02)
Synthesis for oxazolo[4,5-d]isoxazole derivatives and 3,4-disubstituted isoxazoles from isoxazol-5(4H)-ones is reported.
An Improved Preparation of 5-Unsubstituted Isoxazoles by Borohydride Reduction of 5-Chloroisoxazoles
Ponticelli, Fabio,Tedeschi, Piero
, p. 792 - 794 (2007/10/02)
The borohydride reduction of 5-chloroisoxazoles offersa useful and unambiguous way to 5-unsubstituted isoxazoles.
SELECTIVITY IN CYCLOADDITIONS-XII THE DIRECTIVE EFFECT OF ENOL ETHERS AND THIOENOL ETHERS IN CYCLOADDITIONS OF NITRILE OXIDES
Caramella, P.,Bandiera, T.,Gruenanger, P.,Albini, F. Marinone
, p. 441 - 453 (2007/10/02)
Cycloadditions of nitrile oxides to 2,3-dihydrofuran are highly regioselective whereas the regioselectivity of the cycloadditions to 2,3-dihydrothiophen is only moderate.The directing effect of oxygen and sulfur in these cycloadditions could be evaluated
