The structurally unique antifungal antibiotic ambruticin (1) has been prepared for the first time in a convergent synthesis. The strategy for its synthesis involved the independent preparation of the enantiomerically pure fragments 19, 31 and 49. The required C(7)C(8) β-C-glycoside bond was formed by coupling the glycosyl fluoride 19 with the in situ formed vinyl alane derivative 32. Formation of
