Mechanochemical Solvent-Free Synthesis of Indenones from Aromatic Carboxylic Acids and Alkynes

The mechanochemical solvent-free synthesis of indenones from aromatic carboxylic acids and alkynes was achieved through triflic anhydride (Tf2O)-induced cyclization reaction. A variety of indenones including a bioactive PPARγagonist were obtained in up to 90% yield at room temperature. The present protocol has the advantages of mild reaction conditions, high reaction efficiency, and feasibility of scalable synthesis, providing a facile and sustainable route to diverse indenones.

MeOTf-induced carboannulation of arylnitriles and aromatic alkynes: A new metal-free strategy to construct indenones

MeOTf-induced carboannulation of arylnitriles and aromatic alkynes for synthesis of indenones under metal-free conditions has been described. When ortho-substituted benzonitriles were used, indeno[1,2-c]isoquinolines were formed.

Der konformative ortho-Effekt bei o-Tolylstilbenen und deren Vinyllithiumderivaten

Geometrical isomers of stilbene derivatives with an additional, o-substituted phenyl moiety at the CC double bond (5, 6, 13) are prepared and structurally assigned.The isomer with the two phenyl groups in trans-position is favoured in equilibrium (conform
