We have achieved the totalsynthesis of an architecturally and biologically intriguing cyclic polypeptide, rhizonin A (1), in an exceptionally concise and convergent fashion. The strategic route entails 9 longest linear steps to elaborate commercially available materials into the natural product with an overall yield of 9.7%. The brevity of sequence and high overall yield was fueled by the judicious
The first totalsynthesis and biological evaluation of the naturallyoccurringcyclic heptapeptide rhizonin A are described. The synthesis includes solution-phase peptide synthesis and the preparation of NMe-3-(3-furyl)alanine (NMe-FurAla), a unique component of rhizonin A, which was prepared in chiral form via Barton-MacCombie deoxygenation as a key step. The bioactivity was assessed using 3T3–L1
