Abstract: Secondary metabolites containing oxazole, oxazoline and isoxazoline ring skeletons are widely distributed
in both marine and terrestrial organisms. They possess significant biological activities such as anti-tumor, antibacterial,
anti-viral, anti-malarial and immunosuppressive. The complexity in the molecular structures coupled with
their wide biological properties, has attracted the attention of many synthetic and natural product chemists. The introduction
of multifunctional substituents and the construction of stereo-centers were considered as major challenges
and obstacles in developing synthetic protocol for these classes of compounds. Few review articles on the
total synthesis of oxazole contaning marine natural products namely bengazoles, phorboxazole, pseudopteroxazoles,
hennoxazole and cyclopeptide have been reported till date. However, these reviews omitted the discussion
on isolation and biological activities. In this review, we present the brief account on isolation, relevant biological activities and a recent
development on the total synthesis of marine natural products containing oxazole, oxazoline and isoxazoline ring skeletons reported till
2014.
