Design and synthesis of a bis(hydroxyphenyl)diamide bearing a pendant thiazolium unit; application to the catalytic asymmetric intramolecular Stetter reaction
摘要:
The bis(hydroxyphenyl)diamide architecture constitutes as a privileged ligand that promotes a number of catalytic asymmetric transformations in combination with rare-earth metals. A new diamide analog armed with a carbene catalytic function derived from a thiazolium unit was designed, synthesized, and applied to the catalytic asymmetric intramolecular Stetter reaction. Cooperative work between the carbene function and hydrogen bonding interactions was suggested to give the enantioenriched chroman derivatives. (C) 2014 Elsevier Ltd. All rights reserved.

A copper-catalyzed intramolecular radical cascade acyl-cyanation to synthesize cyano-containing chroman-4-ones has been developed. A series of CN-substituted chroman-4-one derivatives can be prepared with moderate to good yields using green cyano source under mild conditions. Control experiments indicated this reaction involved an intramolecular acyl radical addition/cyanation process. Moreover, this

日期:1997.8.1
The preparation of 2-(2-((tert-butyloxycarbonyl)amino)phenyl)ethyl mercaptan from 2-(2-amino-phenyl)ethanol is described. This thiol is condensed with a series of suitably unsaturated carboxylic acids to give a series of thiol esters. The Boc group is removed and the amine reacted with isoamyl nitrite to give a series of diazonium salts. Exposure to iodide in acetone solution then generates the aryl radical, which undergoes intramolecular homolytic substitution at sulfur with liberation of the acylradical. Following acyl radical cyclization, quenching by iodine and then elimination of HI leads to the isolation of alpha-methylene cycloalkanones in good yield.
