  Synthesis of Biologically Relevant Compounds by Ruthenium Porphyrin Catalyzed Amination of Benzylic C–H Bonds

  摘要：

  Herein we report the catalytic activity of ruthenium porphyrin complexes to promote the amination of benzylic C-H bonds by aryl azides, yielding alpha- and beta-amino esters. The catalytic methodology is also effective to synthesize two derivatives of methyl L-3-phenyllactate in order to convert one of them into the corresponding beta-lactam. The catalytic experimental conditions have been optimized on the basis of a preliminary mechanistic investigation which underlines the pivotal role of the substrate concentration to maximize the reaction productivity.

• Nucleophilic Iron Catalysis in Transesterifications: Scope and Limitations
  作者：Silja Magens、Bernd Plietker

  DOI：10.1021/jo1004636

  日期：2010.6.4

  The ester bond is one of the most common structural motifs found in nature. Apart from the condensation between an acid and an alcohol, transesterifications represent another mechanistic alternative for the preparation of this compound class. The present paper summarizes our most recent investigations in this field, using nucleophilic iron complexes as catalysts for transesterifications under neutral conditions. This new type of metal catalyst complements the existing methodologies, which rely on Lewis acidic metal complexes. Investigations on scope and limitations, stereochemical course, and chemoselectivities will be presented.

  日期：2019.2.15

  catalyst-controlled intramolecular unactivated C(sp3)-H amination and oxygenation of carbamates merging visible-light photocatalysis and earth-abundant transition metal catalysis have been reported. Useful amino alcohol and diol derivatives could be selectively obtained from readily available tertiary alcohol derivatives. The possible mechanisms have been proposed via a 1,5-HAT process followed by Lewis acid-controlled
