Phorbazoles are chlorinated marine alkaloids containing pyrrole, oxazole and phenol ring units, and differ in the number and positions of chlorine atoms. They are isolated from sea sponges and nudibranchs. In this work, a convenient synthetic method leading to a new phorbazole and its derivatives is developed. This synthesis of synthetic phorbazole G and its derivatives is achieved in seven steps in good overall yields of 26-52%. It involves formation of the pyrrole-oxazole skeleton followed by chlorination. The pyrrole-oxazole skeleton is synthesized from pyrrole and substituted acetophenones, and the key step involves cyclodehydration of amide intermediates to give protected oxazoles, followed by hydrolysis.

Investigations into the parallel synthesis of selected analogues of a structurally unique pyrrole-oxazole analogue of the pyrrole insecticide pirate, are reported. Acylaminoketone salts were obtained from ketobromides in moderate to high yields and excell

The pyrrole oxazole 4 is a novel analogue of the broad-spectrum insecticide and miticide pirate 2. The expedient synthesis of pyrrole oxazole 4 in six steps from pyrrole is reported using a synthetic route that could have potential for the solution-phase
