Abstract

This short review aims at decrypting and analyzing the various strategies used for the synthesis of tiacumicin B. Natural products synthesis is a way for organic chemists to express inventiveness, intellectual dexterity, and elegance in strategy of synthesis. Some molecular structures are more inspiring than others; and if like tiacumicin B, the architectural challenge meets high biological and medicinal interest, the molecule can then attract the attention of many groups of synthetic chemists.
