The Chemistry of Strigolactones (original) (raw)

Strigolactones - Biology and Applications, 2019

Abstract

Focus of this chapter is the chemistry of Strigolactones. The structural features that identify the canonical versus non canonical Strigolactones, as well as the stereochemistry of the Strigol type and Orobanchol type families will be described. A special emphasis will be devoted to the total synthesis of natural Strigolactones as the most reliable and recommended method for successful structure elucidation of these natural products. However, due the complexity of the target molecules and to the high stereochemical control required to retain bioactivity, the synthesis of natural Strigolactones is currently not feasible on a multigram scale for applications in agriculture. In order to study the effect of Strigolactones on various biological processes, model compounds were designed and prepared. Synthetic Strigolactones can be classified into two main categories: (a) analogues, whose structure is very similar to natural SLs; (b) mimics, whose structure is much simpler, but showing a bioactivity resembling that of SLs. A survey of the most promising structures for agricultural applications and the synthetic pathways to access them is herein provided.
