A new set of 2,3,4,5-tetrasubstituted isoxazolidines with an α,β-unsaturated carbonyl function at position 4 has been synthesized. The multicomponent approach and microwave irradiation protocol have also been investigated for the above synthesis.
stereoselective synthesis of a set of new tetra substituted isoxazolidines from 5-substi-tuted 2-methoxybenzaldehydes, N-phenylhydroxylamine and 1-(2-thienyl)-3-arylprop-2-en-1-ones has been achieved. The effect of microwave irradiation on the reaction under solvent-free conditions has also been investigated. The stereochemistry of the final products has been confirmed by NMR and single crystal X-ray
