Stereocontrolled introduction of an amino group at C-6 of D-galactose via (3,3)-sigmatropic rearrangements - Novel synthesis of lincosamine and 7- epi-lincosamine precursors

A new and stereoselective route to the aminoglycoside components of the antibiotics lincomycin and clindamycin is presented. The key step involves diastereoselective introduction of the amino group at C-6 of D-galactose by (3,3)-sigmatropic rearrangements of the corresponding allylic (Z)- trifluoroacetimidate and (Z)- and (E)-allylic thiocyanates. Epoxidation of the resulting trifluoroacetamide with m-CPBA led to the epoxide with high threo-selectivity.
