Popis: | The authors acknowledge the EPSRC and Cancer Research UK (CRUK Grant No. C21383/A6950) for funding this research. Recent reports have highlighted the biological activity associated with a sub-family of the tetramic acid class of natural products. Despite the fact that members of this sub-family act as protein-protein interaction inhibitors of relevance to proteasome assembly, no synthetic work has been reported. This may be because this sub-family contains an unnatural 4,4-disubstitued glutamic acid, the synthesis of which provides a key challenge. Here we describe a highly stereoselective route to a masked form of this unnatural amino acid. This enabled the synthesis of two of the possible diastereomers of JBIR-22 and allowed its relative and absolute stereochemistry to be assigned. Publisher PDF |
