method for constructing the four contiguous nitrogen-containing stereogenic centers of SB-203207 by using as key steps the stereoselective alkylation of bowl-shaped tricyclic lactone to construct a quaternary carbon at C1, the stereoselective hydroboration–oxidation reaction to install the C2 hydroxy group, and the Curtius rearrangement to introduce a nitrogen atom onto the C1 quaternary carbon.
