Streszczenie:
The beginning of 1970’s may well be regarded as turning point in the area of organic synthesis when an efficient and straight forward strategy for the reaction of primary and/or secondary alcohols with variety of nucleophiles in the presence of triphenylphosphine and azodicarboxylate reagent was discovered by O. Mitsunobu and since then rapid progress has been made in understanding and applying the Mitsunobu reaction for various derivatization reactions. Due to versatile applications and mild reaction conditions associated with the said strategy, the Mitsunobu reaction has received much attention in the last almost fifty years and has been well reported. The basic objective of this review is to pay attention on the recent advances and applications of the Mitsunobu reaction particularly in last decade. The attention has also been paid to describe various modifications which have been explored in the traditional Mitsunobu reaction by substituting P (III) reagents or azodicarboxylate reagents with other suitable reagents or else using an organocatalyst with the objective to improve upon the traditional Mitsunobu reaction. In the present review we wish to report the major advancements achieved in last few years which are likely to be beneficial for the researchers across the globe.

Streszczenie:
The Mitsunobu reaction basically consists in the conversion of an alcohol into an ester under inversion of configuration, employing a carboxylic acid and a pair of two auxiliary reagents, mostly triphenylphosphine and a dialkyl azodicarboxylate. This reaction has been frequently used in carbohydrate chemistry for the modification of sugar hydroxy groups. Modification at the anomeric position, leading mainly to anomeric esters or glycosides, is of particular importance in the glycosciences. Therefore, this review focuses on the use of the Mitsunobu reaction for modifications of sugar hemiacetals. Strikingly, unprotected sugars can often be converted regioselectively at the anomeric center, whereas in other cases, the other hydroxy groups in reducing sugars have to be protected to achieve good results in the Mitsunobu procedure. We have reviewed on the one hand the literature on anomeric esterification, including glycosyl phosphates, and on the other hand glycoside synthesis, including S- and N-glycosides. The mechanistic details of the Mitsunobu reaction are discussed as well as this is important to explain and predict the stereoselectivity of anomeric modifications under Mitsunobu conditions. Though the Mitsunobu reaction is often not the first choice for the anomeric modification of carbohydrates, this review shows the high value of the reaction in many different circumstances.

Streszczenie:
The Mitsunobu reaction plays a vital part in organic chemistry due to its wide synthetic applications. It is considered as a significant reaction for the interconversion of one functional group (alcohol) to another (ester) in the presence of oxidizing agents (azodicarboxylates) and reducing agents (phosphines). It is a renowned stereoselective reaction which inverts the stereochemical configuration of end products. One of the most important applications of the Mitsunobu reaction is its role in the synthesis of natural products. This review article will focus on the contribution of the Mitsunobu reaction towards the total synthesis of natural products, highlighting their biological potential during recent years.

The first 1,5- and 2,5-disubstituted fluorous tetrazoles are sought as potential surfactants. Direct alkylation of monosubstituted tetrazoles using alkyl iodides and triflates is compared with the Mitsunobu reaction. Mitsunobu conditions provide advantage for perfluoroalkylethylation, in terms of selectivity towards the 2,5-isomers and overall yield, but are not applicable to perfluoroalkylmethylation.

Streszczenie:
The Mitsunobu reaction has emerged as an important alternative for the preparation of synthetic 2′-deoxynucleosides, which have various biological and biotechnological applications. In this work, the Mitsunobu-based synthesis of 2′-deoxynucleosides was systematically studied. The effect of phosphine, azodicarbonyl reagent, and solvent on the product yield and α/β ratio was investigated, and the highest yield and β-selectivity were obtained using (n-Bu)3P and 1,1′-(azodicarbonyl)dipiperidine in DMF. The reaction was successfully applied to various nucleobase analogues.

Streszczenie:
Nucleophilic substitution reactions of alcohols are among the most fundamental and strategically important transformations in organic chemistry. For over half a century, these reactions have been achieved by using stoichiometric, and often hazardous, reagents to activate the otherwise unreactive alcohols. Here, we demonstrate that a specially designed phosphine oxide promotes nucleophilic substitution reactions of primary and secondary alcohols in a redox-neutral catalysis manifold that produces water as the sole by-product. The scope of the catalytic coupling process encompasses a range of acidic pronucleophiles that allow stereospecific construction of carbon-oxygen and carbon-nitrogen bonds.

Streszczenie:
In order to convert 1′H-benzimidazol-2′-ylpropanols into aryl ethers using Mitsunobu coupling, it was necessary to protect the benzimidazole nitrogen in the starting alcohols. Selective protection at nitrogen was achieved through N-benzyl derivatives, but attempts to protect the nitrogen directly through tert-butoxycarbonyl, acetyl, trityl, or tetrahydropyranyl derivatives were complicated either by selective reactions at oxygen or by the formation of bis-protected compounds. Transformations of some oxygen-protected derivatives are discussed, and in particular the conversion of the acetates of 1′H-benzimidazol-2′-ylpropanols to N-tetrahydropyranyl derivatives is described. Mitsunobu coupling involving the N-benzyl and N-tetrahydropyranyl derivatives and methyl 4-hydroxybenzoate were achieved, and thus afforded synthetic routes to the desired propylbenzimidazole aryl ethers.
