A new approach for the functionalization of C-4 of isoquinolines is reported. The method utilizes palladium catalyzed, hetero-atom guided (or electrophilic metalation) direct arylation via regioselective C-H functionalization of dihydroisoquinolines.

A Pd-catalyzed cross-coupling reaction of α-alkoxytosylhydrazones with sulfonates derived from salicyl aldehydes gives rise to protected 1,5-dicarbonyl compounds. Treatment with ammonium hydroxide readily transforms these alkenes into isoquinolines with d
Easy access to isoquinolines and tetrahydroquinolines from ketoximes and alkynes via rhodium-catalyzed C-H bond activation

(Chemical Equation Presented) Described herein is a convenient and highly regioselective synthesis of substituted isoquinoline derivatives from various aromatic ketoximes and alkynes via a one-pot, rhodium-catalyzed C-H bond activation. In addition, tetra
Isoquinoline syntheses via Δ2-oxazolines. Part VIII cyclization of 2-acetamido-1,2-diphenylethan-1-ol derivatives into isoquinoline systems
Kopczynski,Voelkel
, p. 1317 - 1325 (2007/10/03)
The results of the conversion of 2-acetamido-1,2-diphenylethan-1-ol derivatives (1) into 1-methyl-4-phenylisoquinoline derivatives (2) have been described. The mechanism proposed for these reaction assumes the existence of protonated Δ2-oxazolines (3), carbonium ions (4), and unsafurated amides (5 and 6) as intermediates.

Shklyaev, V. S.,Dormidontova, E. V.,Saraeva, R. F.
, p. 1088 - 1089 (2007/10/02)
1-Methyl-4-aryl-7-R-isoquinolines were obtained by cyclization of 1,1-diaryl-2-acetamidoethylenes in the presence of phosphorus pentoxide.The condensation of the products with diethyl oxalate leads to the formation of ethyl 1-(4-aryl-7-R-isoquinolyl)pyruv
