Conjugate addition reactions of alpha-aminoalkylcuprates with alpha,beta-alkenyl-, alpha,beta-alkynyl-, alpha,beta-beta,gamma-allenyl-, and alpha,beta-gamma,delta-dienyl carboxylie acid derivatives, nitriles, and sulfoxides

alpha -Aminoalkylcuprates prepared from alpha -lithio carbamates and CuCN.2LiCl participate in 1,4-addition reactions with alpha,beta -unsaturated esters, thiol esters, imides, and nitriles in poor to excellent yields depending upon the electron-withdrawing substituent and the substitution pattern of the unsaturated substrate. These reagents also undergo conjugate addition reactions with alpha,beta -alkynyl esters, sulfoxides, and nitriles and with alpha,beta-beta,gamma -unsaturated allenyl esters. Excellent stereocontrol is achieved in the conjugate additions of alpha -aminoalkylcuprates to the allenyl esters, while poor stereoselectivity results in the conjugate additions to the alkynyl derivatives. Deprotection and cyclization of the alkynyl adducts affords pyrrolin-2-ones, while similar treatment of the allenyl adducts affords 4-alkylidine- pyrrolidin-2-ones and pyrrolizidinones.

A novel stereoselective tin-free radical protocol for the enantioselective synthesis of pyrrolidinones and its application to the synthesis of biologically active GABA-derivatives

Optically pure 4-alkyl-pyrrolin-2-ones were synthesized from chiral N-allyl-alpha-bromoacetamides in high selective and stereo-controlled fashion, via a sequential 5-exo-trig radical cyclization-hydrogen or bromine atom-transfer process, under non-tin conditions. Interestingly, when N-allyl-alpha-bromoacetamides were treated with triethylborane/MeOH(excess)/BF3 center dot OEt2 in toluene at -78 degrees C, a tandem 5-exo-trig radical cyclization-hydrogen atom-transfer reaction operated, on the other hand, a tandem 5-evo-trig radical cyclization-bromine atom-transfer reaction proceeded in good yield and high stereoselectivity when the reaction was carried out with equimolar amounts of MeOH in THF at -78 degrees C. Thus, optically pure 4-alkyl-pyrrolin-2-ones were synthesized via this tin-free radical pathway and transformed to their corresponding biologically active GABA-derivatives, Pregabalin and CAMP.

Magnetically enhanced polymer-supported ceria nanocatalysts for the hydration of nitriles

The heterogeneous catalysis of the hydration of nitriles to amides is a process of great industrial relevance in which cerium(IV) oxide (also referred to as ceria) has shown an outstanding catalytic performance. The use of non-supported ceria nanoparticles is related to difficulties in the purification of the product and the recovery and recyclability of the catalyst. Therefore, in this work, ceria nanoparticles are supported on a polymer matrix either by synthesizing polymer particles by so-called Pickering miniemulsions while using ceria nanoparticles as emulsion stabilizers or, as a comparison, byin-situcrystallization on preformed polymer particles. The former strategy presents significant advantages over the latter in terms of time and consumption of resources, and it facilitates an easier scale-up of the process. In both strategies, the incorporation of a magnetoresponsive core within the polymer matrix allows the recovery and the recycling of the catalyst by simple application of a magnetic field and offers an enhancement of the catalytic efficiency.
