  A Labeled Substrate Approach to Discovery of Biocatalytic Reactions: A Proof of Concept Transformation with N-Methylindole

  摘要：

  Biocatalysis has become an important method in the pharmaceutical industry for the incorporation of new functionality in small molecules. Currently this method is limited in the types of reactions that can be carried out and no strategy exists to systematically screen for new biocatalyzed reactions. This study involves the development of a medium throughput screen to identify and optimize new reactions using a series of marine-derived bacterial cell lines, which were screened against several C-13 labeled organic substrates. The reactions were analyzed using C-13 NMR as the primary screening tool. We describe the discovery of a bacterial catalyzed indole oxidation reaction in which complete conversion of C-13 labeled N-methyl indole to 3-hydroxyindole was observed. In addition, the sensitivity of this reaction to dO(2) levels can be exploited to oxidize to either 3-hydroxyindole or 2-oxoindole. This new platform sets up an important tool for the discovery of new organic transformations using an extensive library of marine bacteria.

  benzofurans, and furans, to unactivated terminal and internal alkenes. The reaction is catalyzed by a combination of Ni(COD)2 and a sterically hindered, electron-rich N-heterocyclic carbene ligand or its analogous Ni(NHC)(arene) complex. The reaction is highly selective for anti-Markovnikov addition to α-olefins, as well as for the formation of linear alkylheteroarenes from internal alkenes. The reaction occurs

• Acid-catalyzed isomerization of 3-indolyl sulfides to 2-indolyl sulfides: first synthesis of 3-unsubstituted 2-arylthioindoles. Evidence for a complex intermolecular process

  The acid-catalyzed isomerization of 3-indolyl sulfides 1 to the corresponding 2-indolyl sulfides 4 provides the first synthesis of 3-unsubstituted 2-(arylthio)indoles, a hitherto unattainable class of compounds. When catalyzed by trifluoroacetic acid, the isomerization proceeds mainly via an intermolecular mechanism involving initial disproportionation to a 2,3-indolyl bis-sulfide 5 and an unsubstituted counterpart 6 followed by further interaction of these species to yield the rearranged isomer 4. A mechanism is proposed involving a role for the acid in the sulfenyl-transfer steps. This type of process also occurs, to a lesser extent, in the polyphosphoric acid catalyzed isomerization.
