1,3-DIPOLAR CYCLOADDITION: MOLECULAR SIEVES ASSISTED GENERATION OF NITRILE OXIDES FROM HYDROXIMOYL CHLORIDES
Molecular sieves irrespective of their pore size convert hydroximoyl chlorides into the corresponding nitrile oxides very slowly and cleanly in the presence of dipolarophiles to give isoxazolines in good to excellent yields.

Some Acylations of 3-Phenyl and 3-Mesityl-4,5-dihydroisoxazoles
A study on the acetylation and benzoylation of title compounds by quenching the corresponding 4-carbanions with acyl chlorides or esters is reported.The obtained ketones are formed as minor regioisomeric adducts in the cycloadditions of benzo and mesitoni
