Current Organic Synthesis - Volume 5, Issue 4, 2008

The paper presents recent work conducted in our group on the synthesis of a novel class of homogeneous and immobilized Rucomplexes containing Schiff bases as O,N-bidentate ligands benefiting from a versatile, quite general and thoroughly exemplified twostep procedure. The new Ru-complexes with improved stability incorporate a variety of Schiff bases, associated with traditional inorganic and organic ligands such Read More

Chiral sulfur ligands which have been developed quite recently bu us are reviewed. Several types of chiral sulfur ligands, which involve a chiral sulfoxide group as a sole chiral source, and other coordinating elements such as phosphine, nitrogen, oxygen, sulfur, and so on, have been developed. A role of the chiral sulfoxide functions as ligands in metal-catalyzed asymmetric synthesis has been revealed by the X-ray cr Read More

Recent advances in the development of environmentally benign solid acid-catalyzed Friedel-Crafts reactions are reviewed. The work includes two main chapters, alkylations and acylations. The data are summarized based on the chemical nature of the reagents used, such as alkenes, alkyl halides and alcohols/ethers in alkylation, while activated carboxylic acid derivatives and carboxylic acids in acylation. Special topics in bo Read More

The utility of ruthenium-based catalysts in the construction of furan and pyrrole derivatives is reviewed. Among others, synthetic approaches involving cycloisomerization, ring-closing metathesis and multicomponent reactions are discussed.

In this review reactivity of uracil and its derivatives towards nucleophilic and electrophilic reagents is described. A different approach of uracil derivatives preparation and their application in further synthesis is also mentioned.
