A novel reductive Heck cyclization approach was developed in order to construct a model DEF-benzoxocin ring system that is present in nogalamycin, menogaril, and related anthracycline antitumor antibiotics.

Construction of the DEF-ring system of nogalamycin and menogaril has been achieved with a novel reductive Heck cyclization approach. Our strategy exploited the stereoelectronic preferences dictated by the anomeric effect for introduction of an O-glycosidic bond in order to direct the introduction of a bridging C-glycosidic bond with the desired stereochemistry. Our strategy relied upon a stereoselective
