Abstract
Callystatin A, a polyketide marine natural product, has been known since 1997 after its isolation from the sponge Callyspongia truncata by Kobayashi et al. It belongs to the leptomcyin family of natural products with a highly conjugated and stereodefined skeleton. The challenging structural topographies and remarkable anti-proliferative properties of (−)-Callystatin A stimulated many researchers to pursue the total synthesis of this marine polyketide. This review is exclusively focused on the research undertaken towards the concise, asymmetric total synthesis of Callystatin A over the last two decades. The various target oriented synthetic pathways are discussed in a chronological order to give a comprehensive overview.
期刊介绍：
Cessation. Tetrahedron: Asymmetry presents experimental or theoretical research results of outstanding significance and timeliness on asymmetry in organic, inorganic, organometallic and physical chemistry, as well as its application to related disciplines, especially bio-organic chemistry.
The journal publishes critical reviews, original research articles and preliminary communications dealing with all aspects of the chemical, physical and theoretical properties of non-racemic organic and inorganic materials and processes. Topics relevant to the journal include: the physico-chemical and biological properties of enantiomers; strategies and methodologies of asymmetric synthesis; resolution; chirality recognition and enhancement; analytical techniques for assessing enantiomeric purity and the unambiguous determination of absolute configuration; and molecular graphics and modelling methods for interpreting and predicting asymmetric phenomena. Papers describing the synthesis or properties of non-racemic molecules will be required to include a separate statement in the form of a Stereochemistry Abstract, for publication in the same issue, of the criteria used for the assignment of configuration and enantiomeric purity.
