Ceria nanoparticles as heterogeneous catalyst for CO2 fixation by ω-aminoalcohols
Juarez, Raquel,Concepcion, Patricia,Corma, Avelino,Garcia, Hermenegildo
, p. 4181 - 4183 (2010)
In contrast to γ-Al2O3, TiO2, ZrO2, MgO and Y2O3, CeO2 is a reusable catalyst for the reaction of CO2 with ω-aminoalcohols to form cyclic carbamates; the highest yield (68%) was obtained for the preparation of N-alkyl 1,3-oxazolidin-2-ones from N-alkyl ethanolamines.
Microwave assisted synthesis of unsaturated jasmone heterocyclic analogues as new fragrant substances
Pawelczyk, Anna,Zaprutko, Lucjusz
, p. 3032 - 3039 (2009)
Taking the rising interest in jasmone structure based fragrant compounds into account it has been decided to take up an attempt to synthesize the new heterocyclic derivatives of this 2,3-disubstituted cyclopentenone, which could be characterized by the ability of interaction with the same receptors with which jasmone affects. Obtained structures of unsaturated heterocyclic derivatives are based on pyrrolidinone, oxazolidinone, pyrazolidinone, pyrazolone and thiazolidinone systems with 2-double or 2-triple unsaturated five-carbon side chain. The rapid, highly yielding and ecofriendly microwave assisted organic syntheses (MAOS) have been used to obtain compounds mentioned above. Odor evaluation and relationships between their structure and osmic properties for all synthesized fragrant compounds have been studied. It has been shown that the majority of the obtained compounds have exhibited interesting, very intensive and fixative fragrant properties.
A sustainable protocol for the facile synthesis of zinc-glutamate MOF: An efficient catalyst for room temperature CO2 fixation reactions under wet conditions

A water stable zinc-MOF (ZnGlu) catalyst was facilely prepared from the proteinogenic amino acid, l-glutamic acid at room temperature in aqueous medium. CO2 fixations were promoted by the ZnGlu catalyst's inherently coordinated water and externally added water in yielding cyclic carbonate and cyclic urethane at room temperature. This eliminates the need for catalyst activation, making ZnGlu a ready-to-use catalyst. The enhanced CO2 cycloaddition with added water hints at the application of ZnGlu in wet flue gas conversions. This is the first reported attempt for the use of an MOF in the cycloaddition of aziridine and CO2.

N,N′-Bis(pyridin-2-ylmethyl)oxalamide (BPMO) was found to be an apposite promoter for the Cu-catalyzed N-arylation of oxazolidinones and primary and secondary amides with (hetero)aryl iodides at room temperature. Excellent chemoselectivity reached between
Catalytic Oxidative Carbonylation of Amino Moieties to Ureas, Oxamides, 2-Oxazolidinones, and Benzoxazolones

The direct syntheses of ureas, oxamides, 2-oxazolidinones, and benzoxazolones by the oxidative carbonylation of amines, β-amino alcohols, and 2-aminophenols allows us to obtain high value added molecules, which have a large number of important applications in several fields, from very simple building blocks. We have found that it is possible to perform these transformations using the PdI2/KI catalytic system in an ionic liquid, such as 1-butyl-3-methylimidazolium tetrafluoroborate, as the solvent, the solvent/catalyst system can be recycled several times with only a slight loss of activity, and the product can be recovered easily by crystallization.
