Microwave assisted Pd(OAc)2-catalyzed chemoselective reduction of aryl α,β-unsaturated esters with triethylsilane

< p>In this communication, we have reported that the Pd(OAc)2–Et3SiH-DMF system promotes the microwave-assisted chemoselective reduction of aryl α,β-unsaturated esters in good yields. The protocol affords a convenient reduction of aryl-conjugated double bonds even in presence of other functional groups like esters, phenols, and ethers.

Et3B-mediated and palladium-catalyzed direct allylation of β-dicarbonyl compounds with Morita–Baylis–Hillman alcohols

A practical and efficient palladium-catalyzed direct allylation of β-dicarbonyl compounds with both cyclic and acyclic Morita-Baylis-Hillman (MBH) alcohols, using Et3B as a Lewis acid promoter, is described herein. A wide range of the corresponding functionalized allylated derivatives have been obtained in good yields and with high selectivity.

Palladium-catalyzed regioselective allylation of five-membered heteroarenes with allyltributylstannane.

Palladium-catalyzed allylation reactions of 2-(chloromethyl)thiophenes, 2-(chloromethyl)furans, and N-protected 2-(chloromethyl)-1H-pyrroles with allyltributylstannane were described in this study. This type of allylation reaction regioselectively occurred on the heteroarene rings to produce allylated dearomatization products or allylated heteroarenes with satisfactory yields.

Palladium-Catalyzed Allylation/Benzylation of H-Phosphinate Esters with Alcohols.

The Pd-catalyzed direct alkylation of H-phosphinic acids and hypophosphorous acid with allylic/benzylic alcohols has been described previously. Here, the extension of this methodology to H-phosphinate esters is presented. The new reaction appears general, although its scope is narrower than with the acids, and its mechanism is likely different. Various alcohols are examined in their reaction wi...

Microwave Assisted Synthesis of N-Benzylenaminones Catalyzed by Chloroacetic acid

Benzylaminoalkenones and benzylaminoalkenoates 3 were synthesized from reaction of benzylamine with corresponding 1,3-diketones and 1,3-ketoesters in the presence of catalytic amount of chloroacetic acid under microwave radiation. This method offers several advantages including high yield of products, recyclable of the catalyst and easy experimental work-up procedure.
