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.).

Bond activation in action: Unprecedented ruthenium-catalyzed oxidative annulations of alkynes through cleavage of C-H bonds set the stage for an efficient 1(2H)-isoquinolone synthesis with ample scope (see scheme; tAm=tert-amyl). Mechanistic studies provided strong evidence for a rate-limiting C-H bond metalation through carboxylate assistance. Copyright

A methodology for the high yield and facile synthesis of isoquinolones from benzamides and alkynes via the oxidative ortho C-H activation of benzamides has been developed. Ag2CO3 proved to be an optimal oxidant when MeCN was used as
