Concise assignments of the C5′ stereochemistry in (+)-lepadin F and (+)-lepadin G, and the absolute configuration of (+)-lepadin G via the first total syntheses of (+)-5′-epi-lepadin F, (+)-lepadin G, and (+)-5′epi-lepadin G are described. This work represents an illustrative example in which a diastereomeric pair can possess sufficient spectroscopic difference for clear assignment despite differing only at a highly insulated acyclic stereocenter.
