  Synthesis and structural revision of eurypamides isolated from the Palauan sponge Microciona eurypa

  摘要：

  Eurypamides A and B, 1 and 2, were successfully synthesized by employing Tl(NO3)(3) (TTN) oxidation of the corresponding halogenated phenols, 9, 16, and 26. This investigation revealed that the dihydroxyarginine residue of 1 should be revised to possess (2S,3R,4S)-configuration. In addition, the synthesis of 2 provided a pure sample, which was previously characterized in a mixture. (C) 2003 Elsevier Ltd. All rights reserved.

  Total synthesis of eurypamides A, B, and D, 1, 2, and 4, has been successfully accomplished. The Tl(NO3)(3) (TTN) oxidation of the halogenated bisphenols, 14a, 14b, 24, and 43, effected regio-controlled cyclization to provide the corresponding diaryl ethers, 15a, 15b, 25, and 46. This investigation revealed a structural revision of eurypamide A as to possess (2"S,3"R,4"S)-configuration (47), along with the spectral data of pure 2 and 4, which were previously characterized in a mixture.
