A novel and convenient method for the synthesis of 3, 5-diarylisoxazoles

α,β-Unsaturated oximes of chalcones on treatment with 2,3-Dichloro- 5,6-dicyano-1,4-benzoquinone (DDQ) in methanol furnish 3,5-disubstituted isoxazoles in good yield.

Aerobic oxidative synthesis of 3,5-disubstituted isoxazoles directly from α,β-unsaturated ketones

Using an efficient aerobic oxidative method, the synthesis of ten 3,5-disubstituted isoxazoles by treatment of α,β-unsaturated ketones with hydroxylamine and NaOH at room temperature has been achieved.

A direct access to isoxazoles from ynones using trimethylsilyl azide as amino surrogate under metal/catalyst free conditions

A general method for isoxazoles from readily available ynones using trimethylsilyl azide as an amino surrogate, likely via an unprecedented hydroazidation of the alkyne and denitrogenative cyclization, is demonstrated. The method neither required any cata

A convenient preparation of 3,5-diarylisoxazoles

3,5-Diarylisoxazoles 2a-i were prepared in moderate to high yields 51-94%) by oxidation of chalcone oximes with a new metal complex oxidant, tetrakis(pyridine)cobalt(II) dichromate (TPCD).
