该中间体在本合成路线中的序号：(XVa)In an improved synthesis, condensation of the beta-dimethyltetramethylene-ferrocene derivative (XIV) with aldehyde (II) produced the unseparable C-20 epimeric mixture (XV) without appreciable amounts of diastereomeric byproducts. Cleavage of the chiral auxiliary group with HOAc under milder conditions furnished the secondary amines (XVI) with minimal C-3,C-7 epimerization. Benzylation of amines (XVI) then gave the enantiomerically pure tertiary amines (XIII), which were finally processed as above.
