This book was released on 2015 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: The synthesis and reactions of 2-iodoynamides were investigated. 2-Iodoynamides undergo efficient and regioselective [2 + 2] cycloaddition with ketene to produce cyclobutenones that are useful synthetic building blocks. Reaction of 2-iodoynamides and vinylketenes generated in situ from cyclobutenones proceeds via a pericyclic cascade mechanism to produce highly substituted 2-iodoanilines. Tandem strategies for the synthesis of highly substituted indoles involving this benzannulation reaction were investigated. In addition, the synthesis of furo[2,3-g]thieno[2,3- e]indole, a new tetracyclic aromatic compound, was achieved via a strategy based on benzannulation with ynamides.

This book was released on 2011 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have prepared various substituted cobaloxime dienes and studied extensively their reactivities in Diels-Alder reactions. Based on the studies with cobaloxime chemistry, we concluded that increased exo selectivities were possible with the insertion of the transition metals in the 2-position of the diene moiety. In the first part of this study, we will describe the higher-order [6+4] and Diels-Alder [4+2] reactions of the cobaloxime dienes with various tropones. The reaction pathway [6+4 vs 4+2] largely depends on the substituents on the tropone moiety where as the stero and regioselectivity is determined only by the cobaloxime. In order to overcome the problems persisting with those dienes in catalytic reactions, we have now moved on to main group element substituted dienyl compounds which are benign to nature, easy to handle and mild in reactivities. These main group element substituted dienes can be transmetalated efficiently to catalytic quantities of transition metals in order to get all the enhanced selectivities mentioned above. We have already established the pathway by using boron substituted dienes. Herein, we describe various methods used in the synthesis of stable silyl dienes from inexpensive starting materials and show their improved regio and stereoselective reactions in Diels-Alder, cross-coupling, and domino reactions.
Book Synopsis The Pauson-Khand Reaction by : Ramon Rios Torres
Download or read book The Pauson-Khand Reaction written by Ramon Rios Torres and published by John Wiley & Sons. This book was released on 2012-03-01 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Pauson-Khand reaction is an important reaction in the field of organic chemistry. It involves the transition-metal catalysed cycloaddition of an alkyne, an alkene and carbon monoxide, to produce cyclopentenones. The importance of this reaction originates from its high value in transforming simple components into the synthetically useful cyclopentenone unit, in which a high degree of molecular complexity can be achieved in a single step, with impressive stereochemical and regiochemical control. The Pauson-Khand Reaction investigates the nature and many variations of this reaction. Topics covered include: the mechanisms of Pauson‐Khand-type reactions non chiral intramolecular and intermolecular versions of Pauson‐Khand reactions asymmetric Pauson‐Khand reaction using chiral auxiliaries the enantioselective Pauson‐Khand reaction Pauson‐Khand reactions catalysed by metals other than cobalt unconventional Pauson‐Khand reactions the Pauson‐Khand reaction in total synthesis Presenting a comprehensive overview of this fundamental reaction, The Pauson-Khand Reaction will find a place on the bookshelves of any organic or organometallic chemist.
