Application of Negishi cross-coupling to the synthesis of the cyclic tripeptides OF4949-III and K-13

(Chemical Equation Presented) Syntheses of the cyclic tripeptides OF4949-III 1 and K-13 2 are reported, in which the key steps are intermolecular and intramolecular Negishi cross-coupling reactions, respectively. In addition, the synthesis of a protected

Pd-catalysed C-C macrocyclisation of a simple tripeptide: Efficient total synthesis of K-13

The cyclic tripeptide K-13 has been prepared in 11 steps from commercially available starting materials (11% overall yield); the key step is the Pd-catalysed macrocyclisation of the zinc reagent prepared by selective insertion of zinc into the aliphatic C
