(pasteurellosis) and vibriosis, respectively. A convergent total synthesis of its Ga3+ complex using l-/d-cysteine as chiral agents and Meldrum’s acid is described. A Staudinger reduction/Aza-Wittig process in the synthesis of the acid-sensitive β-hydroxy-2,4-disubstituted thiazoline moiety and the convenient protecting groups was a key step in this synthesis.
