linker moiety to attach amines to the resin by reductive amination. Resin-bound tertiary amines were shown to be readily transferred into the respective liberated N-hydroxylated or N-methylated derivatives by either an oxidation/Cope elimination or a permethylation/Hofmann elimination protocol. With these two divergent liberation/derivatization options, the new resin offers new flexibility in the solid

An efficient totalsynthesis of notoamide J, a new prenylated indole alkaloid and potentialbiosyntheticprecursor, is described herein. Starting from l-proline and a substituted tryptophan derivative, this synthesis also employs an oxidation and pinacol rearrangement for the formation of the oxindole in the final step.
