Download or read book Organocatalytic Enantioselective Conjugate Addition Reactions written by Jose L Vicario and published by Royal Society of Chemistry. This book was released on 2010-10-18 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, unique in its field, is a comprehensive description of all the methodologies reported for carrying out conjugate addition reactions in a stereoselective way, using small chiral organic molecules as catalysts (organocatalysts). In the last 3-4 years, this has been a rapidly growing field in organic chemistry, and many papers have appeared reporting excellent protocols for carrying out these highly efficient transformations that compete well with other classical approaches using transition metal catalysts. A particularly attractive feature of this transformation relies upon the fact that the conjugate addition (Michael and Hetero-Michael reactions) is an extraordinarily effective means to initiate cascade processes which result in the formation of complex molecules from very small and simple starting blocks. The book, written by noted experts, covers all recent advances in this hot topic, and provides a good state-of-the-art review for organic chemists working in this field and all those who wish to start projects in this area.

Download or read book Organocatalytic Michael Addition Reactions of Nitrostyrenes and Application in the Synthesis of Selected Indolizidine and Quinolizidine Alkaloids written by Moorthy Nagamyian Vengada Guru and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The organocatalytic asymmetric conjugate addition of carbon nucleophiles and heteroatom nucleophiles to electron deficient nitroalkenes is an important tool for the synthesis of highly functionalized building blocks for applications in medicinal and synthetic organic chemistry. Although the enantioselective conjugate addition reactions of -nitrostyrenes are well known, the corresponding conjugate addition reactions of - nitrostyrenes are not reported. The present study examines the organocatalytic asymmetric, enamine-mediated conjugate addition reaction of aldehydes or cyclic ketones to -nitrostyrenes that were generated in situ from the corresponding nitroacetates. The details of this study are described in Chapter 2 of this thesis. The utility of the above methodology was demonstrated by application in the formal total synthesis of 4-aryl indolizidine alkaloids, (+)-lasubine II and (-)-subcosine II. The organocatalytic Michael addition of 1,4-cyclohexanedione monoethylene ketal to an appropriate -nitrostyrene which were generated in situ from the corresponding nitroacetate gave the key -nitroketone which was used as the starting material in the alkaloid synthesis. The details of this study are described in Chapter 3. Finally, an enantiomerically enriched -nitroketone obtained from the organocatalytic Michael addition of 1,4-cyclohexanedione monoethylene ketal to a - nitrostyrene has been utilized in the synthesis of a recently isolated indolizidine alkaloid, (+)-fistulopsine B, which is of interest due to its anticancer activity. Details of this investigation are described in Chapter 4.
