Design of a simple and efficient synthesis for bioactive novel pyrazolyl–isoxazoline hybrids†
A simple and new methodology has been developed for the synthesis of novel bioactive pyrazolyl–isoxazoline hybrids from a pyrazolyl-substituted oxime and various substituted allyloxybenzenes, which are easily available, inexpensive starting materials. All the novel synthesized target hybrids were characterized by NMR, IR, and mass spectroscopic techniques. We have employed some of the hybrid materials in anti-bacterial and anti-fungal activity studies. The hybrid materials 6m and 6p exhibited the best anti-bacterial and anti-fungal activities.
