generation of nitrileoxides through NaCl/Oxone oxidation of aldoximes and their dipolar cycloaddition. The key feature is the use of a green chemistry approach to address the substrate scope of aldoximes: broad scope (aliphatic, aromatic, and alkenyl aldoximes) without production of organic byproducts derived from oxidant and/or catalyst. Importantly, NaCl/Oxone-promoted three-component cycloaddition of aldehyde

Routes to dihydrojasmone and γ-keto-aldehydes and an alternative procedure for a key intermediate in our prostaglandin synthesis are described. 2-Isoxazolines are useful intermediates for a preparation of a variety of classes of compounds. A novel route to pyrroles is established.
