Davison EK, Cameron AJ, Harris PWR, Brimble MA. Synthesis of endolides A and B: naturally occurring N-methylated cyclic tetrapeptides. MEDCHEMCOMM 2019; 10:693-698. [PMID: 31191859 DOI: 10.1039/c9md00050j] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/29/2019] [Accepted: 03/01/2019] [Indexed: 01/16/2023]
Abstract
Endolides A and B are naturally occurring, N-methylated, cyclic tetrapeptides possessing an unusual 3-(3-furyl)alanine amino acid and outstanding biological profiles. 1-Propanephosphonic anhydride (T3P) was used to mediate a solution-phase cyclisation reaction of the linear tetrapeptides, thus achieving the first syntheses of both endolides A and B. The stereoselectivity of the tetrapeptide cyclisation reactions was found to be reagent-controlled, and was independent of the C-terminal configuration of the linear peptide starting materials.
