Metathesis of aniline and 1,2-dihydroquinoline derivatives
Evans, Paul,Grigg, Ronald,Monteith, Michael
, p. 5247 - 5250 (1999)
Ring closing metathesis of N,N-diallylanilines and a related 1,2- dihydroquinoline, catalysed by Grubbs' catalyst, occurs in good yield at room temperature furnishing 3-pyrrolines and 3-piperidines. DCM and EtOAc are the solvents of choice and interesting substituent effects are identified and discussed.

The Mizoroki-Heck reaction of N-alkenyl-substituted 2-haloanilines is an effective protocol for the synthesis of substituted 4-alkylidene- tetrahydroquinoline derivatives, avoiding isomerization and oxidation. When non-substituted alkenes are used, the regioselectivity of the reaction can be directed towards the formation of an exocyclic or endocyclic double bond by choosing an adequate catalytic system. When the double bond is substituted by an amide moiety, the exocyclic double bond of E geometry is obtained selectively. Thus, this protocol efficiently synthesizes a series of 2-substituted tetrahydroquinolines with an exo α,β-unsaturated amide moiety at the C-4 position. Optimal conditions for Mizoroki-Heck reactions of N-alkenyl-substituted 2-haloanilines have been developed to access 4-alkylidene-tetrahydroquinoline derivatives regioselectively, avoiding isomerization and oxidation.

Observations on the intramolecular Heck reactions of aromatic chlorides using palladium/imidazolium salts
Caddick, Stephen,Kofie, William
, p. 9347 - 9350 (2007/10/03)
The intramolecular Heck reaction of aromatic amines and ethers using palladium/imidazolium salts is described. The use of tetra-n-butylammonium halide salts facilitates the reactivity of aromatic chlorides. An unexpected and novel palladium-mediated cyclisation is also described leading to the formation of a tricyclic adduct.
