supporting information; experimental part, p. 6840 - 6842 (2009/04/06)
Mastering unusual amino acids: The first total synthesis of the potent protease inhibitor cyclotheonamide C (see structure representation) has been achieved. The key features of the synthesis are a three-component tandem procedure to create a masked α-keto-β-arginine within a peptide chain, and the control of the extended conjugation of a vinylogous α,β-dehydrotyrosine.

A synthetic equivalent of the southern segment of cyclotheonamide C, a cyclopentapeptide isolated from the sponge Theonella, has been synthesized via complementary Wadsworth-Emmons or palladium-catalysed methodologies followed by tandem oxidation/vinyloga
