چکیده
N-Cinnamoyl-9-aminoanthracenes cyclise with PPA or triflic acid to form novel 2-azahexacyclo[10.6.6.0(1,5).0(6,11).0(13,18).0(19,24)]tetracosa-6(11),7,9,13,15,17,19(24),20,22-nonaen-3-ones. In contrast, both N-cinnamoyl-N-methyl-9-(2-aminomethyl)anthracene and N-cinnamoyl-9-(2-aminoethyl)anthracene undergo an intramolecular Diels-Alder cycloaddition.

A comprehensive review of the oxidative cyclisation of 2’-hydroxychalcones to aurones and flavones
The oxidative cyclisation reactions of 2’-hydroxychalcones to corresponding aurones and flavones are discussed. While Hg2+, Cu2+ and Tl3+-mediated oxidative cyclisation of 2’-hydroxychalcones selectively give aurones, I2, Se4+, In3+, Cu+ and Fe3+-mediated reactions preferable give flavones. The general mechanisms of these oxidative cyclisation reactions are proposed.
متن کاملPalladium-catalysed cyclisation of alkenols: Synthesis of oxaheterocycles as core intermediates of natural compounds
The study of Pd-catalysed cyclisation reactions of alkenols using different catalytic systems is reported. These transformations affect the stereoselective construction of mono- and/or bicyclic oxaheterocyclic derivatives depending on a starting alkenol. The substrate scope and proposed mechanism of Pd-catalysed cyclisation reactions are also discussed. Moreover, the diastereoselective Pd-catal...
متن کاملAtom transfer radical cyclisation reactions mediated by copper complexes.
This article describes recent advances in the use of copper complexes in mediating atom transfer radical cyclisation reactions (ATRC). Recent developments have included the design of activated complexes which mediate the cyclisation of tri-, di-, and mono-halo derived substrates at ambient temperatures. Using this methodology, cyclisation to give a variety of ring sizes (4-18 membered rings) ha...

متن کاملThe Baylis-Hillman approach to quinoline derivatives.
Baylis-Hillman reactions of 2-nitrobenzaldehydes with various activated alkenes afford adducts that undergo reductive cyclisation to quinoline derivatives. The chemo- and regioselectivity of cyclisation appears to be influenced by the choice of both the substrate and the reagent system, and competing reactions have been observed.
