4-(Z)-propenylproline [(4-PE)Pro]. The latter two have never been found in any natural product before. The side chain of 1 is terminated with the residue of 5-chloro-1-hydroxypyrrole-2-carboxylic acid [Chpca]. This first synthetic access to hormaomycin 1 will make it possible to prepare structural analogues of this interesting natural depsipeptide in order to elucidate structure-activity relationships and the biologically

hydrochloric acid, with subsequent purification by ion-exchange chromatography and crystallization. The absolute configurations of the nickel complexes 9a−e were established by X-ray crystallographic analyses. In addition, the X-ray crystal structure of (2S,1′S,2′R)-3 was determined to confirm the convergence of the configurations of the parent nickel complexes 9 with those of the amino acids 3 derived
