Description and Uses
A convergent synthesis of the proposed structure of (+)-pestalazine B has been achieved in 4 steps using the N-alkylation of an unprotected tryptophan diketopiperazine with a 3a-bromopyrrolidinoindoline where the condensation between L-tryptophan methyl ester and N-Fmoc-D-leucine in the presence of EDC as coupling agent afforded the corresponding L-Trp-D-Leu dipeptide.
