Maharani, Rani published the artcileA total synthesis of a highly N-methylated cyclodepsipeptide [2S,3S-Hmp]-aureobasidin L using solid-phase methods, Computed Properties of 77128-73-5, the publication is Tetrahedron (2014), 70(14), 2351-2358, database is CAplus.
[2S,3S-Hmp]-Aureobasidin L 2 has been successfully synthesized through a combination of solution- and solid-phase peptide synthesis. All of the Fmoc-protected residues including a depsidipeptide, Fmoc-MeVal-Hmp-OH, were prepared in solution phase. Chain elongation on chlorotrityl resin was undertaken using selected coupling reagents including HBTU/HOBt, HATU/HOAt and BTC/collidine. Cleavage of the linear depsinonapeptide was followed by cyclization to give the desired cyclodepsipeptide.
