Zeo-Click Synthesis: Copper-Zeolite-Catalyzed Synthesis of Ynamides. ADV SYNTH CATALADV SYNTH CATAL. 2014;356 :3842-3848.
AbstractCopper(I)-zeolites, especially copper(I)-ultra stable Y zeolite (USY), are very efficient heterogeneous catalysts for the coupling of functionalized 1-bromoalkynes and various nitrogen derivatives. Under these conditions, sulfonylated alkyl- or arylamines and various N-heterocycles, such as oxazolidinones or indoles, could be efficiently transformed into the corresponding N-alkynyl derivatives. However, imidazoles gave addition products rather than coupling products. The reaction conditions proved compatible with a variety of functional and protecting groups. Such zeolitic catalysts can be recycled and reused at least five times without significant deactivation. Low catalyst loading could be used (4 mol%) and as low as 0.8 mol% of this heterogeneous copper catalyst still gave good conversion and yields.

An Algorithm Reformulation of XQuery Queries Using GLAV Mapping for Mediator-based System. Journal of Applied Computer Science & Mathematics [Internet]. 2014;(16) :20-26.
Publisher's VersionAbstract
-
This paper describes an algorithm for reformulation of XQuery queries. The mediation is based on an essential component called mediator. The main role of the mediator is to reformulate a user query, written in terms of global schema, in queries written in terms of sources schemas. Our algorithm is based on the principle of logical equivalence, simple and complex unification, to obtain a better reformulation. It takes as parameter the query XQuery, the global schema (written in XMLSchema), mappings GLAV and gives as a result a query written in terms of sources schemas. The results of implementation show the proper functioning of the algorithm.
