transfer of stereogenic information. Utilizing this reaction in natural product synthesis gives access to non-proteinogenic amino acids such as (2S,9S)-2-amino-8-oxo-9,10-epoxydecanoic acid (Aoe), the unusual amino acid of a series of histone deacetylase inhibitors (HDACi). Herein the first totalsynthesis of Cyl-1, a cyclotetrapeptide from Cylindrocladium scoparium, is described.

text] An efficient and highly stereoselective synthesis of cryptophycin B (2), a potent cytotoxic agent, is described. The ester-derived titanium-enolate-mediated syn-aldol reaction was employed to generate the stereocenters C(5) and C(6). The route is convergent and provides a convenient access to the synthesis of structural variants of cryptophycin B as well as members of its family.
