Synthesis of fused tetracyclic spiroindoles via palladium-catalysed cascade cyclisation.
Efficient palladium-catalysed cascade cyclisation to form spiroindoles is developed. Treatment of indoles bearing a propargyl chloride side chain at the 3-position with various external nucleophiles in the presence of a catalytic amount of Pd2(dba)3·CHCl3/dppb and Cs2CO3 in THF gives fused tetracyclic spiroindoles in moderate to good yields.
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

متن کاملL-proline: An efficient catalyst for the synthesis of quinoline derivatives in aqueous media
An efficient and direct procedure for the synthesis of benzo[h]-indeno[1,2-b]-quinoline derivatives has been described. The procedure employs a three-component condensation reaction in one-pot using 2H-indene-1, 3-dione, naphthalen-1-amine,and aldehydes in the presence of catalytic amount of L-prolinein aqueous media.
