Nickel-Catalyzed Sonogashira Coupling Reactions of Nonactivated Alkyl Chlorides under Mild Conditions

The two nickel chlorides1and2with [P,S] and [P,Se] bidentate ligands, respectively, were synthesized and used as catalysts for Sonogashira coupling reaction. Both1and2are efficient catalysts for Sonogashira C(sp3)-C(sp) coupling reactions. Comp

Annulation of Hydrazones and Alkynes via Rhodium(III)-Catalyzed Dual C-H Activation: Synthesis of Pyrrolopyridazines and Azolopyridazines

Hydrazones readily synthesized from N-aminopyrroles or N-aminoazoles and aldehydes undergo Rh(III)-catalyzed dual C-H activation and coupling with aryl- A nd alkyl-substituted alkynes to give pyrrolopyridazines or azolopyridazines, respectively. This transformation represents a rare example of hydrazoyl C-H activation and proceeds without heteroatom functionality to direct C-H activation. Hydrazones derived from aromatic, alkenyl, and aliphatic aldehydes were effective inputs, and tethering the alkyne to the hydrazone enabled annulations to more complex, tricyclic products.

Triflic acid-catalyzed cascade cyclization of arenyl enynes via acetylene-cation cyclization and Friedel-Crafts type reaction

A novel triflic acid-catalyzed cascade cyclization of arenyl 1,7-enynes through acetylene-cation cyclization followed by Friedel-Crafts reaction has been described. Various fused poly carbocycles can be obtained in good to high yields under mild reaction

Indium(III)-catalyzed coupling between alkynes and aldehydes to α,β-unsaturated ketones

The combined use of a catalytic amount of InX3 (X = OTf and NTf2) and 1-butanol was found to be effective in formal alkynealdehyde metathesis. With this catalytic system, aromatic alkynes reacted with aromatic aldehydes to give chalcones in moderate to good yields. Alkynals were efficiently converted into 5- to 7-membered cyclic compounds by intramolecular alkyne-aldehyde coupling.

CAPSAICIN DERIVATES AND THE PRODUCTION AND USE THEREOF

The invention relates to new compounds, namely capsaicin derivates, a new method for their production, and their use as micro-organism-repellent agents in paints and coatings, in particular for marine installations and ships, but also for land-based struc

Iodotrimethylsilane-induced cyclization of 6-alkynal acetals

Treatment of 7-phenyl-6-heptynal dimethyl acetal with iodotrimethylsilane afforded 2-(1-iodobenzylidene)cyclohexyl methyl ether via the intramolecular nucleophilic attack of the carbon-carbon triple bond to the oxonium ion generated by the action of iodotrimethylsilane.
