Burgess reagent in organic synthesis.

In recent years there hasbeen a revival of interest in the Burgess reagent [] due to its versatilityin synthetically useful transformations that have facilitated functionalgroup conversions.

The synthesis of organometallic and coordination compounds has attracted interest among chemists during the past few decades. Organometallic compounds are organic molecules containing at least one atom of a metal bonded to a carbon atom. A familiar example of this class of substance is tetraethyl lead, which was often added to the gasoline that fuels internal-combustion engines. Other organometallic compounds include catalysts used in plastic manufacture and in organic synthesis.

developed an efficient and convenient synthesis of syntheticallyuseful nitrile oxides from primary nitro-alkanes by using the Burgessreagent.

Methylphytylbenzoquinone was synthesized from δ-tocopherol by a simple two-step sequence. Oxidative cleavage of the benzopyran ring with cerium sulfate followed by dehydration using Burgess reagent afforded the methylphytylbenzoquinone as a mixture of positional and geometric isomers which were separated by HPLC. The biological activity of the product corresponds to the natural biosynthetic precursor of vitamin E. The above method is a general procedure applicable to the preparation of any of the tocopherol derivatives.

Azulene is an organic compound and an isomer of naphthalene

Makara and co-workersreported that the Burgess reagent (1) canbe used to activate carboxylic acids and can be treated with aminesto synthesize acyl ureas and amides under microwave irradiation.

Whereas naphthalene is colourless, azulene is dark blue

Nicolaou and co-workers reported a convenient method for the synthesisof both α- and β-glycosylamines in the presenceof the Burgess reagent (1).

Christian Friebe was born in Erfurt (Germany) and studied chemistry at the Friedrich Schiller University Jena (Germany) where he graduated in organometallic chemistry in 2008. He conducted his Ph.D. thesis on the electrochemical and spectroscopic characterization of transition metal complexes at the Friedrich Schiller University Jena under the supervision of Prof. U.S. Schubert and achieved his Ph.D. in 2013. He currently works as a postdoctoral fellow in group of Prof. U.S. Schubert in the field of energy storage materials.

A simple method for the synthesis of carbamate-protected guanidines from primary amines is described. A variety of thioureas derived from primary amines and isothiocyanates react with the Burgess reagent to give the corresponding guanidines via either a stepwise or one-pot procedure. By tuning the carbamoyl units of isothiocyanates and the Burgess reagent, differentially -diprotected guanidines can be obtained. Selective deprotection of the products affords monoprotected guanidines.

The common precursor 1-methoxy-2-prenyl-3-carbomethoxycarbazole was synthesized from dimethyl indolylmethylenesuccinate in four steps. Well-planned reductive and/or oxidative transformations and intramolecular cyclizations were performed on a pivotal common precursor to accomplish collective first total synthesis of titled natural products and proposed claulamine E. Burgess reagent induced formation of kinetically controlled product claulamine A, and intramolecular cyclizations to form bicyclic claulansine A were the key reactions. An alternatively attempted synthesis failed to provide the structural isomer of proposed claulamine E.
