title: Synthesis of an L-proline modified mimetic of the A83586C antitumour cyclodepsipeptide.
abstract: A mimetic of the A83586C cyclodepsipeptide has been synthesised via a three-segment coupling protocol involving dipeptides 9, 8 and 7; in contrast to our previous synthesis of A83586C, where the HATU-mediated macrolactamisation proceeded in 25% yield, the corresponding macro-lactamisation of seco-amino acid 18 occurred in ca. 78% yield.
