Tryptophan-based dimeric diketopiperazine alkaloids such as ditryptophenaline, WIN
64821, naseseazine A, and naseseazine B, exhibit a unique architecture and interesting
biological activity. These alkaloids have been the subject of intense study by the
synthetic organic chemistry community, and several elegant total syntheses have been
discovered, especially using bioinspired strategies. Described herein is a brief overview
of these alkaloid syntheses via bioinspired transformations as key steps.
