Graphical Abstract

Spot the difference: Conformational analysis of the 2S,4R and 2S,4S epimers of N-acetyl-4-mercaptopyrrolidine-2-carboxylic acid methyl esters reveals ring-pucker preferences that are opposite of those of the hydroxyproline derivatives (see scheme). Replacement of proline or hydroxyproline in polypeptides with the chalcogen analogue should allow for fine-tuning of the complex interplay of noncovalent interactions, steric hindrance, and stereoelectronic effects.
