Abstract

Even today, when planar structures of natural products can be determined with microgram samples, the configurational assignment continues to be a challenge. The relative and absolute configurations of natural products can be assigned by devising original approaches, relying on carefully acquired data on a case-bycase basis. In this review, the most widely available methods and techniques for the absolute configuration determination of novel natural products are concisely discussed. Selected illustrative examples (case studies) are presented, where original approaches integrating different chemical, spectroscopic, and/or computational methods have been devised to solve intriguing stereochemistry issues of natural small molecules.
