supporting information, p. 8731 - 8735 (2019/11/03)
Chalkophores are bacterial natural products that chelate and transport extracellular copper. The diisonitrile natural product SF2768 was first isolated from a Streptomyces species as an antifungal antibiotic and has more recently been characterized as a bacterial chalkophore and potential virulence factor. Herein, we report a modular synthesis of SF2768 and related acyclic analogues, allowing assignment of syn-stereochemistry across the central lactol ring. The copper-binding properties of these diisonitriles have also been studied.
A practical and simple synthesis of (2S,5R)- and (2S,5S)-5-hydroxylysine and of a related α-amino acid required for the synthesis of the collagen cross-link pyridinoline

A four step synthesis of (2S,5R)- and (2S,5S)-5-hydroxylysine using Williams' glycine template methodology for controlling the stereogenicity at the α-position is reported. This route offers the possibility for the synthesis of all possible isomers of 5-hydroxylysine and of an important α-amino acidic iodohydrin required for the construction of the hydroxylated side chain of the collagen cross-link pyridinoline.
Asymmetric syntheses of (2S,3S,6S)-, (2S,3S,6R)-, and (2R,3R,6S)-2,3-methano-2,6-diaminopimelic acids. Studies directed to the design of novel substrate-based inhibitors of L,L-diaminopimelate epimerase

The asymmetric syntheses of (2S,3S,6S)-, (2S,3S,6R)-, and (2R,3R,6S)-2,3-methano-2,6-diaminopimelic acids (7a-c) is described. The synthesis features phosphonate coupling of 13 and 14 to form the corresponding E-olefins which are subsequently cyclopropanated and deprotected under dissolving metal conditions.
Asymmetric Synthesis of 2,6-Diaminopimelic Acids
Williams, Robert M.,Yuan, Chenguang
, p. 6519 - 6527 (2007/10/02)
The preparations of (R,R)-2,6-diaminopimelic acid, (S,S)-2,6-diaminopimelic acid, (S,R)-2,6-diaminopimelic acid, and (S,S)-2,7-diaminosuberic acid are described.The synthesis of mono-N-protected (S,R)-2,6-diaminopimelic acid is also described.
