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

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 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.

In this work, a simple and facile approach is conducted for preparing many new SBA-15 supported dendritic imidazolium ILs heterogeneous catalysts SBA-15/IL(1–3) having high ionic density from SBA-15. SBA-15/IL(3) as a green heterogeneous catalyst can be used for synthesis of 2-imidazolidinone from ethylenediamine and carbon dioxide and considering solvent-free condition. SBA-15/IL(3) showed to have the highest catalytic activity besides a positive dendritic influence on the yields of the synthesis of 2-imidazolidinone in the presence of CO2 is seen because of existing the high-density peripheral zwitterionic ionic liquid functional groups on the biobased SBA-15/IL(3) catalyst surfaces.

Efficient synthesis of 2-oxazolidinones from epoxides and carbamates catalyzed by amine-functionalized ionic liquids

, p. 71765 - 71769 (2015/09/08)
A series of amine-functionalized ionic liquids were prepared and their catalytic performance was tested in the synthesis of 2-oxazolidinones from epoxides and carbamates. Under optimized reaction conditions, good to excellent yields of various 2-oxazolidinones were achieved with different epoxides and carbamates. Moreover, the amine-functionalized ionic liquid catalyst could be easily recovered and reused without significant loss in activity.
