The synthesis of isokidamycin, which represents the first total synthesis of a bis-C-aryl glycoside natural product in the pluramycin family, has been completed. The synthesis features the use of a silicon tether as a disposable regiocontrol element in an intramolecular Diels-Alder reaction between a substituted naphthyne and a glycosyl furan and a subsequent O -> C-glycoside rearrangement.

highly efficient Diels–Alder reaction between a substituted naphthyne and a glycosylated furan to form the anthracene core bearing a pendent angolosamine C-glycoside. The regiochemical outcome of the Diels–Alder reaction was controlled by employing a disposable silicon tether to link the reactive naphthyne and the glycosyl furan, rendering the cycloaddition intramolecular. The benzopyranone moiety of
