Visible-light-excited 9,10-phenanthrenequinone (PQ*) was used as a photocatalyst for the synthesis of polysubstituted quinolines via the electrocyclization of 2-vinylarylimines. Up to quantitative yields of 2,4-disubstituted quinolines were received after 1 h of excitation with blue LEDs at room temperature when MgCO3 was used as an additive in DCM. On the basis of experimental and DFT studies, we propose that PQ? induces one-electron oxidation of the imine substrate that triggers the electrocyclization mechanism.

We report the first example of palladium-catalyzed phosphoryl-carbamoylation of alkene-tethered carbamoyl chlorides with P(O)H compounds. Both H-phosphinates and secondary phosphine oxides are compatible with this reaction. DPE-Phos was used as ligand to facilitate nonbenzylic C(sp3)?P bonds formations via C(sp3)?Pd(II)?P reductive elimination. By using this protocol, a range of phosphorylated oxindoles and lactams were obtained in moderate to good yields. (Figure presented.).
One-pot ring-closing metathesis/1,3-dipolar cycloaddition through assisted tandem ruthenium catalysis: Synthesis of a dye with isoindolo[2,1-a]quinoline structure

The one-pot tandem reaction of N-alkyl-N-allyl-2-vinylaniline derivatives with benzo- or naphthoquinones and a ruthenium-alkylidene catalyst leads to isoindolo[2,1-a]quinolines in a variety of colors, which can be altered by exchanging the substituent on the core heterocycle (see scheme). This reaction offers a new synthetic method for π-conjugated small molecules from simple aniline derivatives. Copyright

A sequential one-pot process is reported involving in situ, palladium catalysed, formation of a series of tributylstannyl-1,2-carbo and heterocyclic dialkylidene-5-membered rings from the corresponding 1,6-diynes and Bu 3SnH. These substrates a

The synthesis of 3,3-disubstituted and 3-methyleneox-indoles by palladium(0) catalysed cyclisation of carbamoyl chlorides onto proximate alkene or alkyne groups has been achieved in good yields.
