Optimized syntheses of 5,15-diphenylporphyrin (DPP, 1) and its dipyrrolic precursors are described. A novel procedure for the synthesis of dipyrromethane (2), prepared by hydrodesulfurization of the corresponding di-2-pyrrolylthione (8), is presented, as well as an improved method to isolate large q
Syntheses of cyclotetradepsipeptides, AM-toxin 111 and two analogs, were achieved, in which the Hofmann degradation method was used in order to derive a dehydroalanine residue from a 2,3\_diaminopropionic acid residue in cyclodepsipeptide precursors. AM-Toxins (Fig. 1) are host-specific phytotoxic
