Preparation of dicarboxylate analogues of Cerulenin
Moseley, Jonathan D.,Staunton, James
, p. 819 - 830 (2007/10/03)
We have proposed and synthesized several new structural classes of Cerulenin analogues, which have potential as inhibitors of both fatty acid and polyketide synthase multi-enzyme complexes. These analogues contain cis epoxides bearing flanking carboxylate groups. Our syntheses have been designed to allow access to a wide range of fatty acid and polyketide-like side chains from readily available starting materials in convergent fashion in just four to five steps. In total, ~40 potential analogues have been prepared and characterized, covering all the structural sub-classes proposed, the majority of which constitute novel functional groupings.
Synthesis of an optically active 4-acetoxyazetidinone intermediate for penems and carbapenems
Habich,Hartwig,Born

The synthesis of the novel (3R,4R)-4-acetoxy-3[(1S)-1-t-butyldimethylsilyloxymethyl-1-((1S)-1-ph nylethylaminocarbonyl)]azetidin-2-one, a valuable key intermediate for penems and carbapenems bearing a 6-hydroxyacetamide side chain, and its diastereomer 1b
A Powerful New Stereo-controlled Method for Epoxidation of Electrophilic Alkenes
Clark, Carol,Hermans, Patricia,Meth-Cohn, Otto,Moore, Clive,Taljaard, Heinrich C.,Vuuren, Gerda van
, p. 1378 - 1380 (2007/10/02)
t-Butyl hydroperoxide and an alkyl-lithium in dry tetrahydrofuran are shown to epoxidise α,β-unsaturated esters and sulphones efficiently in a stereo- and regio-specific manner, while esters of chiral alcohols undergo diasterefacially selective epoxidatio
