Rhizocticins and Plumbemycins are natural phosphonate antibiotics produced by the bacterial strains Bacillus subtilis ATCC 6633 and Streptomyces plumbeus, respectively. Up to now, these potential threonine synthase inhibitors have only been synthesized under enzymatic catalysis. Here we report the chemical stereoselective synthesis of the non-proteinogenic (S,Z)-2-amino-5- phosphonopent-3-enoic acid [(S,Z)-APPA] and its use for the synthesis of Rhizocticin A and Plumbemycin A. In this work, (S,Z)-APPA was synthesized via the Still-Gennari olefination starting from Garner's aldehyde. The Michaelis-Arbuzov reaction was used to form the phosphorus-carbon bond. Oligopeptides were prepared using liquid phase peptide synthesis (LPPS) and were tested against selected bacteria and fungi.
Unsaturated amino acids

, (2008/06/13)
The invention relates to unsaturated amino acids of the formula I STR1 in which R1 represents hydroxy or etherified hydroxy, R2 represents hydrogen, alkyl, hydroxy or etherified hydroxy, R3 represents hydrogen, alkyl, haloalkyl, hydroxyalkyl, lower alkoxyalkyl, arylalkyl, lower alkenyl, halogen or aryl, R4 represents hydrogen, alkyl or aryl, R5 represents hydrogen or alkyl, R6 represents carboxy or esterified or amidated carboxy, R7 represents amino or amino substituted by alkyl or acyl, A represents unsubstituted or alkyl-substituted α,ω-alkylene having from 1 to 3 carbon atoms or represents a bond, and B represents methylene or a bond, with the proviso that A is other than a bond when B represents a bond, and salts thereof. They can be manufactured, for example, in accordance with the Michaelis-Arbuzov reaction and can be used as pharmacologically active substances.
