induction and the other involving an enantiomeric synthesis. The latter route gave the desired products in greater than 96% de, whereas the synthesis based on asymmetric induction resulted in only 80% de in the final product. Evaluation of the two diastereomers as inhibitors of spermidine synthase showed that the R diastereomer is a more potent inhibitor than the S diastereomer.

were assayed as inhibitors of spermidine synthase, and both 2b and 3b were found to be potent inhibitors of the enzyme. The thioether 2b is the most potent inhibitor of spermidine synthase described to date and is almost totally devoid of inhibitory activity against the closely related aminopropyltransferase, spermine synthase. This type of compound should have use as a specific inhibitor of spermidine
