The first totalsynthesis of the postulated structure of the aminolipopeptide trichoderin A and itsepimer are reported. A late-stage solution phase C-terminal coupling was employed to introduce the C-terminal aminoalcohol moiety. This methodology provides a foundation to prepare analogues of trichoderin A to establish a structure–activity relationship. NMR spectroscopic analysis established that the

The postulated structure of the potent anticancer peptaibol culicininD has been synthesized using Fmoc-based solid-phase peptide synthesis (SPPS). Comparison of the 1H NMR data for the reported structure of culicininD with the data obtained for the two synthetic polypeptides epimeric at C-6 in the AHMOD unit established the C-6 stereochemistry of the AHMOD residue in the natural product to be (R)

An improved second-generation synthesis of the unnatural amino acid components of the anticancer peptaibol culicininD has been developed. With a protected glutamic acid derivate as the starting material, the process readily delivered the Fmoc-protected free acid derivatives of AHMOD ((2S)-amino-(6R)-hydroxy-(4S)-methyl-8-oxodecanoic acid) and AMD ((2S)-amino-(4S)-methyldecanoic acid) required to support
