TL;DR: This review aims to fill the void and analyze the diversity of structurally unique natural products containing spirocyclic moieties of various sizes and their relative populations with unique compounds reported in the literature.
Abstract: Spirocyclic motifs are emerging privileged structures for drug discovery. They are also omnipresent in the natural products domain. However, until today, no attempt to analyze the structural diversity of various spirocyclic motifs occurring in natural products and their relative populations with unique compounds reported in the literature has been undertaken. This review aims to fill that void and analyze the diversity of structurally unique natural products containing spirocyclic moieties of various sizes.
