influenza neuraminidase inhibitor prodrug oseltamivir phosphate (Tamiflu) from cheap, commercially available d-ribose is described. The main features of this approach comprise a metal (Zn, In)-mediated domino reaction and ring-closing olefin metathesis (RCM) of the resultant functionalized dienes to produce the Tamiflu skeleton. The synthesis described in this Letter represents a new and efficient transformation
