Organic Synthesis and Carbon-Carbon Bond Forming Reactions

Acyl anion equivalents which exhibit Umpolung (reversed polarity p 907). Two S atoms attached to the same carbon atom of a 1,3-dithiane cause the H atoms to be more acidic (pKa about 32) than normal alkyl C-H.

Rongalite: A Useful Green Reagent in Organic Synthesis

I extend congratulations to László Kürti and Barbara Czakó for a truly fine accomplishment and a massive amount of work that made it possible. The scholarship and care that they brought to this task will be widely appreciated because they leap out of each page. I hope that this wonderful team will consider extending their joint venture to other regions of synthetic chemical space. Job well done!

5)The enolate ions formed on deprotonation can be alkylated and acylated offering useful products.

Alkenylcopper complexes, easily generated through carbocupration, are useful for the introduction of a vinyl group in the β position of a carbonyl compound. In this case, as above, magnesium bromide is serving as an activating Lewis acid.

These are not very useful generally as there are four potential products. However, they can be useful if one component has no -H.

The book covers many varied and useful reactions for the synthesis of complex molecules, and in a remarkably clear, authoritative and balanced way, considering that only two pages are allocated for each. This is done with unusual rigor and attention to detail. Packed within each two-page section are historical background, a concise exposition of reaction mechanism and salient and/or recent applications. The context of each example is made crystal clear by the inclusion of the structure of the final synthetic target. The referencing is eclectic but extensive and up to date; important reviews are included.

A Useful and Inexpensive Chemical for Organic ..

This book on "Strategic Applications of Named Reactions in Organic Synthesis" is destined to become unusually useful, valuable, and influential for advanced students and researchers in the field. It breaks new ground in many ways and sets an admirable standard for the next generation of texts and reference works. Its virtues are so numerous there is a problem in deciding where to begin. My first impression upon opening the book was that the appearance of its pages is uniformly elegant and pleasing – from the formula graphics, to the print, to the layout, and to the logical organization and format. The authors employ four-color graphics in a thoughtful and effective way. All the chemical formulas are exquisitely drawn.

Very useful method for alkene synthesis as the position of the double bond is known. The first step is formation of a Phosphorus Ylide (a neutral compound with C- and P+).

Today’s organic chemist is faced with the challenge of navigating his or her way through the vast body of literature generated daily. Papers and review articles are full of scientific jargon involving the description of methods, reactions and processes defined by the names of the inventors or by a well-accepted phrase. The use of so-called “named reactions” plays an important role in organic chemistry. Recognizing these named reactions and understanding their scientific content is essential for graduate students and practicing organic chemists.
