Synthetic studies towards carzinophilin: Synthesis and ammonium hydroxide-induced rearrangement of the epoxi-acid fragment

England, Pamela,Chun, Keun Ho,Moran, Edmund J.,Armstrong, Robert W.

, p. 2669 - 2672 (2007/10/02)

An efficient synthesis of the epoxide-containing fragment 4 of carzinophilin has been completed. Intramolecular acyl transfer of a related epoxide afforded amide 16. Comparison by 1H NMR of 4 and 16 with authentic natural product provides further evidence for structural revision of carzinophilin.
