  Synthesis of Indolylpyrimidines via Cross-Coupling of Indolylboronic Acid with Chloropyrimidines: Facile Synthesis of Meridianin D

  摘要：

  Palladium catalyzed cross-coupling reaction of 3-indolylboronic acid with 2,4-dichloropyrimidines proceeded regioselectively to yield indolyl-or bis(indolyl)pyrimidines in high yield, depending on the projection of 3-indolylboronic acid. The marine indole alkaloid meridianin D and an analogue were synthesised via the palladium catalyzed cross-coupling reaction as a key step.

• The formal total synthesis of dragmacidin B, trans-dragmacidin C, and cis- and trans-dihydrohamacanthins A
  作者：Neil K. Garg、Brian M. Stoltz

  日期：2005.4

  A facile formal total synthesis of dragmacidin B, trans-dragmacidin C, and cis- and trans-dihydrohamacanthins A is presented. Our approach to these bis(indole) alkaloids involves a one-pot, four-step cross-coupling/deprotection sequence where complete halogen selectivity is observed. A related approach to access the dihydrohamacanthins is also described.

  properly substituted bis(indole) pyrazine, the skeleton of a marine alkaloid dragmacidin D, has been developed. The key steps involved the regioselective introduction of two indole units, using the palladium(0)-catalyzed Suzuki and the Stille cross-coupling reactions sequentially.

  A series of novel monoindolyl-4-trifluoromethylpyridines and bisindolyl-4-trifluoromethylpyridines was designed and synthesized as potential antitumor agents. They were evaluated for preliminary cytotoxic activity against P388 and A-549 cells with IC50 values. 4-Trifluoromethyl-2,6-bis[3'-(N-tosyl-6'-methoxyl-indolyl)] pyridine was identified as the most potent in this series.

  Mono(indolyl)-4-trifluoromethylpyridines and bis(indolyl)-4-trifluoromethylpyridines were synthesized using Suzuki cross-coupling reaction between 2-chloro-4-trifluoromethylpyridine 9, 2,6-dichloro-4-trifluoromethylpyridine 6 or 2,6-dichloro-3-cyano-4-trifluoromethylpyridine 23 and N-tosyl-3-indolylboronic acid 10. They were evaluated for cytotoxic activity against P388 and A-549 cells with IC50 values. 4-Trifluoromethyl-2,6-bis[3'-(N-tosyl-6'-methoxylindolyl)]pyridine 18 was identified as the most potent in this series.

  DOI：10.1016/s0040-4039(01)00229-5

  日期：2001.3

  Optically active alpha -indolyl N-substituted glycines were synthesized by reaction of an indolyl boronic acid with glyoxylic acid using chiral methylbenzylamine as the chiral auxiliary with high diastereoselectivity. The absolute configuration of the product was determined by a single-crystal X-ray analysis. (C) 2001 Elsevier Science Ltd. All rights reserved.
