A synthesis of brasilibactin A, a cytotoxic siderophore from the actinomycete of Nocardia brasiliensis, and three unnatural diastereomers of the natural product is described. Four possible diastereomers of the β-hydroxy acid fragment were prepared via asy

Amamistatin A, a linear lipopeptide and a growth inhibitor of human tumor cell lines from an actinomycete, was efficiently synthesized by a convergent approach. The asymmetric synthesis of β-hydroxy acid fragment was achieved by using chiral oxazaborolidinone mediated aldol reaction. The oxazole ring was constructed from N-acylthreonine via side-chain oxidation and cyclodehydration. The synthesis of the linear peptide was carded out in a stepwise manner from the cyclic hydroxamic acid fragment, and the final deprotection provided amamistatin A. (C) 2000 Elsevier Science Ltd.
