Benzoxazole Alkaloids: Occurrence, Chemistry, and Biology

Benzoxazole alkaloids exhibit a diverse array of structures and interesting biological activities. In spite of the extensive research done on the synthesis and biology, till date there is no concise update on this class of alkaloids. This chapter summarizes the literature on benzoxazole alkaloids till March 2017, which covers their isolation, characterization, possible biosynthetic origins, biological activities, and major synthetic approaches. These alkaloids have been broadly classified in the context of their sources, namely (i) fungal origin, (ii) marine origin, and (iii) plant origin.
