Stereoselective Synthesis of Dienyl-Carboxylate Building Blocks: Formal Synthesis of Inthomycin C
摘要:
A direct synthesis of stereodefined halodienes is reported. Those key building blocks enable a concise access to polyenic products, as demonstrated in a modular synthesis of Inthomycin C.

The Stille coupling between a common oxazole vinyl iodide and stereodefined stannyl-diene units is described as the cornerstone of a unified synthetic route to the inthomycin family of bioactive Streptomyces metabolites. This procedure has been utilised to prepare (+)-inthomycin B and (+)-inthomycin C for the first time; in these examples the stereogenic centre was introduced using the Kiyooka ketene acetal/amino acid-derived oxazaborolidinone variant of the Mukaiyama aldol reaction. In addition, a convenient preparation of rac-inthomycin A is described based on the same strategy. (C) 2008 Elsevier Ltd. All rights reserved.
