2-amino alcohol precursor is described. These syntheses confirmed that the proposed structures and absoluteconfigurations of hyacinthacines B3, B4, and B5 were correct and disclosed that the proposed structure of hyacinthacine B7 was incorrect. Our synthetic and spectroscopic studies suggest that the natural hyacinthacines B5 and B7 are the same compounds; however, without access to authentic samples
