Felpin et al. developed a palladium-catalyzed tandem Heck reaction-reduction-cyclization synthesis of oxindoles (n=0) and dihydroquinolones (n= 1) using different 2-(2-nitrophenyl)aaylates (n=0) or 2-(2-nitrobenzyl)aaylates (n=l) and aryldiazonium salts 36 in good yield [15] (Scheme 6.7). However, a complementary approach was developed by the same group using diazonium salts 40 and substituted acrylates 41 to access a larger substitution pattern on the C3 position (Scheme 6.8). It is noteworthy that a different solvent was required and the charcoal had to be added after the Heck reaction. C3-unsubstituted, arylated, and alkylated dihydroquinolones 42 can be obtained efficiently using this protocol. [Pg.230]
