convergent formal total synthesis of Polyoxin J was achieved. Two fragments, deoxypolyoxin C and 5-O-carbamoylpolyoxamic acid, were synthesized in a highly stereoselective manner from the common chiral building block, 4-O-benzyl-2,3-O-isopropylidene-L-threose, finishing the formal synthesis of Polyoxin J.
