description

Abstract The absolute configurations at the carbinol centers in several acetogenins were determined through p-bromophenylurethane derivatives and subsequent Mosher ester methodology. This method has been applied on α,α′-dihydroxylated adjacent bis-THF acetogenins with a threo/cis/threo/cis/erythro relative configuration membrarollin (1), a new acetogenin isolated from Rollinia membranacea seeds, rollimembrin (2), membranacin (3) and rolliniastatin-1 (4), and a threo/trans/threo/translerythro relative configuration motrilin (5), squamocin (6), and desacetyluvaricin (7). 1 was found to be the most potent inhibitor of the mammalian mitochondrial complex I.
