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, our strategy proved to be widely applicable and also enabled the reaction of alkenes to provide access to alkenylated benzamides. The methodology was also extended towards the synthesis of isoquinoline alkaloids derivatives viz. oxyavicine and a dipeptide. The developed protocol is simple and cheap, avoids tedious workup procedures and works efficiently under MW irradiation. (Figure presented.).

Ghosh, Subhash Chandra,Ngiam, Joyce S.Y.,Seayad, Abdul M.,Tuan, Dang Thanh,Johannes, Charles W.,Chen, Anqi
, p. 4922 - 4925 (2013/09/02)
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.

, p. 619 - 621 (2007/10/02)
Lead tetra-acetate oxidation of α-hydroxyimino aroylhydrazones of biacetyl (1) gives 1-aroyloxy-4,5-dimethyl-1,2,3-triazoles (2), the structures of which were confirmed by X-ray analysis. A mechanism for this reaction is discussed. The products (2) are effective aroylating agents for the amino function under mild conditions.
