  Cytosporone E: racemic synthesis and preliminary antibacterial testing

  摘要：

  The antibiotic cytosporone E (isolated from the broth of the endophytic fungi CR 200 (Cytospora sp.) and CR 146 (Diaporthe sp.)) was synthesized as a racemic mixture. The key step in the synthesis is the Meyers ortho-alkylation of a chiral aromatic oxazoline. Preliminary antibiotic activity shows antibiosis against Gram-positive bacteria but not Gram-negative bacteria as previously reported. (C) 2004 Elsevier Ltd. All rights reserved.

• Titanium-Catalyzed Stereoselective Synthesis of Spirooxindole Oxazolines
  作者：Joseph J. Badillo、Gary E. Arevalo、James C. Fettinger、Annaliese K. Franz

  DOI：10.1021/ol1027305

  日期：2011.2.4

  A regio- and stereoselective cyclization between isatins and 5-methoxyoxazoles has been developed using catalytic titanium(IV) chloride (10 or 20 mol %) to afford spiro[3,3'-oxindoleoxazolines] in excellent yield (up to 99%) and diastereoselectivity (dr >99:1). Substitution at the 4-position of the oxazole controls nucleophilic attack to provide either the 2-oxazoline or 3-oxazoline spirocycle with excellent (>99:1) regiocontrol.
