  A practical and efficient regioselective synthesis of several new chiral 4,5,6,7-tetrahydro[1,2,3]triazolo[1,5-a]pyrazines is described from α -amino acid derivatives following intramolecular 'click' reaction as the key step. The method obviates product -purification; to obtain the pure triazole products, only the solvent needs to be evaporated.

  LpxC inhibitors are new-type antibacterial agents developed in the last twenty years, mainly against Gram-negative bacteria infections. To develop novel LpxC inhibitors with good antibacterial activities and biological metabolism, we summarized the basic skeleton of reported LpxC inhibitors, designed and synthesized several series of compounds and tested their antibacterial activities against Escherichial

  The BF3·Et2O promoted coupling of tetra-O-benzyl-α-D-galactopyranosyl trichloroacetimidate with a silyl enol ether carrying an oxazolidine ring leads to the α-C-glycosylmethyl ketone (32%, 95% ds) that is converted into the title α-C-glycosyl amino acid by carbonyl oxygen removal (Barton–McCombie) and oxidative cleavage (Jones) of the heterocyclic ring, and into the β-isomer by anomerization and the same two-step sequence.

  For the first time, the [2,3]-Meisenheimer rearrangement has been developed into a general strategy for the construction of chiral tertiary alcohols. The effectiveness and practicality of this methodology are illustrated by the successful synthesis of (R)-20 and (R)-30, the side chain acids of homoharringtonine and harringtonine, respectively.
• An improved method for culturing Streptomyces sahachiroi: Biosynthetic origin of the enol fragment of azinomycin B
  作者：Gilbert T. Kelly、Vasudha Sharma、Coran M.H. Watanabe

  日期：2008.2

  Azinomycin B is an environmental DNA crosslinking agent produced by the soil microorganism Streptomyces sahachiroi. While the agent displays potent cytotoxic activities against leukemic cell lines and animal mouse models, the lack of a consistent supply of the natural product has hampered detailed biological investigations on the compound, including its mode of action and biosynthesis. We report here a significant methodological improvement in the culturing of the bacterium, which allows reliable and steady production of the natural product in good yields. The key experimental step involves the culturing of the strain on dehydrated plates, followed by the generation of a two-stage starter culture and subsequent fermentation of the strain under nutrient-starved conditions. We illustrate use of this culture system by investigating the formation of the enol fragment of the molecule in isotopic labeling experiments with threonine and several advanced precursors (beta-ketoamino acid 3, beta-hydroxyamino aldehyde 4, and beta-ketoaminoaldehyde 5). The results unequivocally show that threonine is the most advanced precursor accepted by the NRPS (non-ribosomal peptidyl synthetase) machinery for final processing and construction of the enol moiety of the natural product.
