Abstract
The Mitsunobu reaction involves the “redox” condensation of an acidic pronucleophile with a primary or secondary alcohol promoted by a reactive phosphonium salt derived from an alkyl or aryl phosphine and an azo compound. The synthetic utility of the reaction is demonstrated by the wide range of acidic pronucleophiles that are tolerated including carboxylic acids, phenols, imides, hydroxamates, thiols, thioamides, fluorinated alcohols, oximes, pyridinium and imidazolium salts, pyrimidine bases, β-ketoesters and trimethylmethane tricarboxylate (TMET) thereby generating a variety of functionally diverse molecules. The focus of this review is to highlight the recent development of new or alternative reagents and purification strategies for the Mitsunobu reaction with a discussion of their suitability for modern drug design supported by selected examples from the literature.

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
Chemistry and Biology of Carbohydrates
Carbohydrates are one of the most abundant natural products and are considered to be extremely important biomolecules for their ever-increasing impact on chemistry and biology. Their role in several important biological processes, notably energy storage, transport, modulation of protein function, intercellular adhesion, malignant transformation, signal transduction, viral, and bacterial cell ...read more
