Tandem oxidative amidation of benzyl alcohols with amine hydrochloride salts catalysed by iron nitrate
摘要:
A tandem process for the oxidative amidation of benzyl alcohols with amine hydrochloride salts has been developed using inexpensive Fe(NO3)(3) as the catalyst, air and aqueous t-butyl hydroperoxide as oxidants. A wide range of benzamides have been synthesized under mild conditions. This greener amide formation method provides an economical and practical assess to benzamides from readily available and inexpensive starting materials. (C) 2013 Elsevier Ltd. All rights reserved.

A microwave‐assisted highly efficient intermolecular C−H functionalization sequence has been developed to access substituted isoquinolones using α‐amino acid esters as a directing group. This methodology enables a wide range of N‐benzoyl α‐amino ester derivatives to react via a Ru‐catalysed C−H bond activation sequence, to form isoquinolones with moderate to excellent yields. As an additional advantage

A systematic study on hippuric acid substituents was performed in order to better understand the influence of stereoelectronic factors on the Erlenmeyer reaction rate. In addition, two reaction systems were evaluated: Hunig's base solvent free conditions and catalytic sodium acetate in 2-methyl-THF. The effect on reaction rate of electron withdrawing and electron donating groups are reported. Specifically, the study led to the conclusion that stereoelectronic factors have significant influence in one of our key Erlenmeyer reaction by affecting its reaction rate.
