Solving the puzzles: Totalsynthesis 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 enabled four rounds of totalsynthesis‐guided structure determination. The pursuit of this alkaloid also led to an improved procedure for indole–aniline
Compounds 7' and 61-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.
