the FGHI ringsystem of azaspiracid is -described. The synthesis features the desymmetrization strategy for the construction of the C27-C33 fragment, Masamune-Roush coupling conditions for the C33-C34 bond formation, and Sharpless asymmetric dihydroxylation as the key steps. One more important feature of this synthetic route is that we can synthesize other -enantiomers of the FGHI ringsystem by changing
