My book summarize with the different methods for synthesis of Isoxazoliens from 2-alkyn-1-one O-methyl oximes ,1, 3-dipolar cycloaddition of phenyl vinylic selenide to nitrile oxides ,reaction of alkenes or alkynes with ketones,Microwave irradiation of propane-l-(1,3-benzodioxol-5-yl)-3-phenyl-l,3-dione with hydroxylamine hydrochloride,Also pyrazoles synthesiszed by 3- Acetyl benzpyrid-4-imno-2-oxime hydrazine hydrate (phenyl hydrazine),2- cyanomethyl benzimidizole -2, 2- dicarboxaldehyde (94) reacts with hydrazine hydrate, condensation of acetic acid azide of hydrazine and/or phenyl hydrazine with ethyl cyanoacetate under fusion afforded the pyrazole.
