Abstract
| - A novel reagent, tert-butyl 2-naphthalenesulfonylcarbamate, has been designed to allow the stepwisesynthesis of secondary aliphatic amines by two consecutiveN-alkylations with intermediate Boc-cleavage and finaldesulfonylation under mild and experimentally convenientconditions. Its application was demonstrated to make anorthogonally protected spermidine derivative, suitable forfurther selective modification. Each individual step, including the final cleavage of 2-naphthalenesulfonyl to providethe secondary amine nitrogen, took place in high yield.
