Reaction of aldoximes with choramine-T leads to formation of nitrile oxides which can react in situ intra- or intermolecularly with olefinic compounds to produce isoxazolines in good yield.

Analogues of the bioactive natural alkoxynaphthalene pycnanthulignene D were synthesized by an efficient method. The starting plant allylalkoxybenzenes (1) are easily available from the plant essential oils of sassafras, dill, and parsley. The target 1-arylalkoxynaphthalenes (5) exhibited antiproliferative activity in a phenotypic sea urchin embryo assay.
