Tandem reactions are of great importance to organic chemists, because of their high efficiency and selectivity by combining multiple reactions in one step.

– Definitely, there is no exception to the semipinacol rearrangement of 2,3-epoxy alcohols and their derivatives. Since the products of the rearrangement normally contain a carbonyl.

It suggests cost-effective routes for the synthesis of valuable industrial and pharmaceutical chemicals. Chapter One introduces the direct synthesis of 5-substituted naphthoquinones and provides extensive information about peri-metalation on naphthalene derivatives.

We successfully developed the methodology for the preparation of 5-substituted naphthoquinones in a concise manner. Synthetically valuable 5-substituted naphthoquinones could be prepared in 4 steps from a commercially available.

You also know that oxidation and reduction reactions occur in tandem: if one species is oxidized, another must be reduced at the same time - thus the term 'redox reaction'. when talking about redox reactions in organic chemistry we. see article for more reactions.

Abstract. A tandem reaction consisting of a Wittig reaction-ring contraction process between α-hydroxycyclobutanone and phosphonium ylides provides highly functionalized cyclopropanecarbaldehydes in very good yield. cesses that includes domino, cascade, or tandem reactions.

All of these terms are commonly used to designate transfor-mation of an organic substrate through two or more individ-ual elaborations with a single workup step [1,5,15,20,23],a sense we shall build on in constructing a parallel terminol-ogy for coupled catalyses.

A reaction of 3-chloro-1,2,4-oxadiazoles with allylamine and diallylamine has been investigated. 3,3a,4,5-Tetrahydroisoxazolo[3,4-d]pyrimidines are produced through a tandem ANRORC/[3 + 2]cycloaddition pathway consisting of the addition of allylamine to the 1,2,4-oxadiazole, followed by ring opening, nitrone formation, and finally cycloaddition.

3-N-Allylamino-1,2,4-oxadiazoles were also. A cascade reaction, also known as a domino reaction or tandem reaction, is a chemical process that comprises at least two consecutive reactions such that each subsequent reaction occurs only in virtue of the chemical functionality formed in the previous step.

In cascade reactions, isolation of intermediates is not required, as each reaction composing the sequence occurs spontaneously.

Handbook of Palladium Catalysed Organic Reactions provides a synoptic description of the main types of reactions which are catalyzed by Palladium and the mechanism which causes these reactions.

Each reaction is presented in graphical form and classified according to the type of transformation involved. Seleno-containing heterocycles exist widely in pharmaceutical molecules and the skeletons of natural products.

The addition of organoselenium to alkenes and alkynes via intramolecular tandem selenocyclization is an efficient method for preparing selenofunctionalized heterocycles.

[Lutz-Friedjan Tietze; Gordon Brasche; Kersten M Gericke] -- Domino reactions belong to a new kind of process development in organic syntheses, and this is the first book on this topic.

ConspectusYnamides are electron-rich heteroatom-substituted alkynes with a C–C triple bond directly attached to the amide group. Importantly, this amide group is able to impose an electronic bias, thus resulting in the highly regioselective attack of this polarized alkyne by a large variety of nucleophiles.

Over the past two decades, catalytic reactions of ynamides have experienced dramatic. A range of alternative mechanisms can usually be postulated for most organic chemical reactions, and identification of the most likely requires detailed investigation. Investigation of Organic Reactions and their Mechanisms will serve as a guide for the trained chemist who needs to characterise an organic chemical reaction and investigate its mechanism, but who is not an expert in physical.

For many years American organic chemists have discussed these prob-lems. The plan of compiling critical discussions of the more important reactions thus was evolved. The volumes of Organic Reactions are collec-tions of about twelve chapters, each devoted to a single reaction, or a definite phase of a reaction, of wide applicability.

The authors. The Wittig olefination utilizing phosphoranes and the related Horner-Wadsworth-Emmons (HWE) reaction using phosphonates transform aldehydes and ketones into substituted alkenes. Because of the versatility of the reactions and the compatibility of many functional groups towards the transformations, both Wittig olefination and HWE reactions are a mainstay in the arsenal of organic.

Book Description. The book provides insight into the working of clays and clay minerals in speeding up a variety of organic reactions.

Clay minerals are known to have a large propensity for taking up organic molecules and can catalyse numerous organic reactions due to fine particle size, extensive surface area, layer structure, and peculiar charge characteristics.

Henry Reaction. The Henry Reaction is a base-catalyzed C-C bond-forming reaction between nitroalkanes and aldehydes or ketones. It is similar to the Aldol Addition, and also referred to as the Nitro Aldol Reaction.

If acidic protons are available (i.e. when R = H), the products tend to eliminate water to give nitroalkenes. Tandem reactions are therefore of increasing importance in modern organic chemistry.

One-pot tandem reactions by virtue of their convergence, elegance, and super-economy are particularly appealing in the context of rapid target-oriented synthesis [ 28 – 30 ].
