Description

CAS: 114360-54-2 | C21H23NO4 | 353.42 g/mol

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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Aplicaciones
Se ha logrado una síntesis convergente de la estructura propuesta de (+)-pestalazina B en 4 pasos utilizando la N-alquilación de una dicetopiperazina de triptófano sin protección con una 3a-bromopirrolidinoindolina donde la condensación entre el éster metílico de L-triptófano y la N-Fmoc-D-leucina en presencia de EDC como agente de acoplamiento proporcionó el dipéptido L-Trp-D-Leu correspondiente.

Solubilidad
Insoluble en agua.

Notas
Almacenar en un lugar fresco. Mantener el recipiente bien cerrado en un lugar seco y bien ventilado. Almacenar lejos de los agentes oxidantes fuertes.
