  Synthesis of the Functionalized Tricyclic Core of Lactonamycin by Oxidative Dearomatization

  摘要：

  [GRAPHICS]We report in this Letter a synthesis of the densely oxygenated CDEF ring system (27) corresponding to that found in the recently discovered antibiotic lactonamycin. The key steps in the synthesis consist of an intramolecular Wessely oxidative lactonization of acid 18, followed by a hydroxyl directed epoxidation of enol ether 21.

  Several kinds of fused cyclic compounds were obtained by tandem Michael-Claisen condensation of ethyl 2-[bis(ethylthio)methyl]benzoate and ethyl 2-[1, 3]dithiolan-2-yl-benzoate with α, β-unsaturated carbonyl compounds. Treatment of the annulated products with mercury(II)perchlorate trihydrate or N-chlorosuccinimide gave naphthoquinones, naphthalenes, and anthracenes.
