Compounds 7′ and 6′-bromo-D-tryptophan (1 and 2) which are important derivatives for the synthesis of the chloropeptin and kistamycin A, respectively, were conveniently synthesized by optical resolution from N-acetyl-7′ and 6′-bromo-DL-tryptophan ((RS)-5 and (RS)-14) using D-aminoacylase.

Solving the puzzles: Total synthesis played a key role in the elucidation of the stereochemistry and verification of the constitution of the complex polymeric natural product psychotetramine. The route features three powerful assembly processes that enabl
Preparation of 7-halo-indoles by thallation of N-formylindoline and their attempted use for synthesis of the right-hand segment of chloropeptin

7-Substituted (Cl, Br, I) indoles were synthesized by using thallation of N-formylindoline as a key reaction. Two precursor tripeptides for the right-hand segment of chloropeptin were synthesized by using (R)-7′-iodo and 7′-bromotryptophans derived from each 7-substituted indole (I, Br) obtained by the above procedure.
