Cycloaddition and cycloisomerization reactions involving alkynes grant a rapid access to arenes, cyclic dienes, and cyclopentenone derivatives. The use of alkynes substituted by group 13 or 14 heteroelements as partners for such reactions is an emerging strategy. Indeed, the specific electronic properties of these heteroelements can play a crucial role for controlling the chemo- and regioselective outcome of a given reaction. M Read More

This review deals with the applications of the Favorskii rearrangement in synthetic Organic Chemistry, paying especial attention to the literature appeared after 1980. The mentioned rearrangement plays a key role in many total synthesis due to the fact that important modifications in the structure of the substrate occur during the process. Skeletal rearrangements in acyclic systems, leading to highly branched carboxylic a Read More

Copper(II) salts are widely applied for the halogenation of aromatic and heteroaromatic systems, the halides. In coupling reactions, CuCl2 has been used as a catalyst for the benzylation of aromates, the synthesis of alkanes, and the preparation of diacetylenes, cyclohexenones and symmetric biaryls. It has further proved suitable for stereoselective cyclization to lactones, carbon-nitrogen coupling and lactamization, and for the Read More

The synthesis of a substituted 2-pyridone ring is a topical area of continuing interest due to the number of biologically active molecules containing this moiety. Over the last decade, natural compounds with this structure have emerged as potent antitumor antiviral and attention, because those compounds may be studied as a simple model for investigating mechanisms of some enzymatic reactions or for discerning the behavior Read More

In the field of molecular biology and biochemistry in which structural genomics comes as a complement to genome sequencing, Small-Angle X-ray Scattering (SAXS) is an experimental technique that, though not widely known and applied, represents a very powerful tool in the framework of post-genome structural studies. The aim of this review is to present a synthetic description of the basic principles of the theory of SAXS Read More
