Synthesis of EFdA via a diastereoselective aldol reaction of a protected 3-keto furanose

An efficient enantioselective total synthesis of EFdA, a remarkably potent anti-HIV nucleoside analogue with various favorable pharmacological profiles, has been achieved in 37% overall yield from diacetone-d-glucose by a 14-step sequence that features a
