Abstract
Abstract The stereoselective synthesis of 4-dehydroxydiversonol (4) employing enantioselective palladium-catalysed domino processes such as the domino Wacker–Heck and the domino Wacker-carbonylation reaction for the formation of the central chroman moiety is described. Thus, reaction of 8 with palladium (II) trifluoroacetate [Pd (OTFA) 2] in the presence of carbon monoxide, methanol and the 2, 2′-bis (oxazolin-2-yl)-1, 1'- ...
