This book was released on 2013 with total page 712 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes three separate research projects within the broad topic of synthetic organic chemistry. The synthesis of alkyl-substituted siloles and their reactivity in Diels-Alder chemistry is reported. Furthermore, the cleavage of the bicyclic adducts by Tamao-Fleming oxidation has been achieved which reveals a highly substituted cyclohexene-1,4-diol structure. The second chapter describes the cycloaddition chemistry of alkoxy-activated cyclobutane dicarboxylates with aldehydes, nitrones and nitrosoarenes. The cycloaddition occurs, in the case of aldehydes, with uniformly high diastereoselectivity to afford tetrahydropyrans in good to excellent yield. When nitrones were used as the dipolarophile the cycloaddition occurs in a rather unselective manner though the formed oxazepanes undergo equilibration to yield single diastereomers in most cases. The cycloaddition with nitrosoarenes, however, proved an exception as the regioselectivity of the reaction was dependant both on the nitrosoarenes and the catalyst employed. Lastly, progress towards the synthesis of grandilodine A is reported. Several routes were developed in attempts to form the central 8-membered ring; however, successful ring closure has eluded this study.

Download or read book Total Syntheses of ( - )-cryptocaryolone and ( - )-cryptocaryolone Diacetate, Progress Towards the Total Syntheses of (±)-sinensigenin A and C and the Development of a Novel Electrophilic Allylsilane Methodology written by Aymara Melvina Margaret Albury and published by . This book was released on 2013 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation highlights the total synthesis of natural products that possess a C-glycoside moiety. The key reaction in the construction of this motif involves an oxocarbenium cationic intermediate. The first chapter of this dissertation looks at total synthesis and its impact on the field of organic chemistry, in addition to a brief summary on C-glycosides and their synthetic preparation via an oxocarbenium cationic intermediate. The second chapter illustrates the total syntheses of ( - )-cryptocaryolone and ( - )-cryptocaryolone diacetate via a diastereoselective oxy-Michael addition and oxocarbenium allylation for the preparation of their [alpha]-C-glycoside subunit. The third chapter describes progress towards the total synthesis of (±)-sinensingenin A and C via a Friedel-Crafts alkylation Marson-type cyclization for the construction of their [beta]-C-glycoside core. The final chapter is dedicated to a methodology study for the preparation of non-conjugated (E)-homoallylic alcohols via a Lewis acid mediated allylation with [alpha]-substituted allylsilanes. This is an intriging discovery because it describes the formation of a new carbon-carbon bond, along with exhibiting high selectivity for the formation of the (E)-olefin moiety, in a single step from the parent aldehyde. Previous methods for the synthesis of these types of molecules would require a minimum of two steps from the same aldehyde precursor.

Book Synopsis Progress Toward the Total Synthesis of the Epoxyquinoid Family of Natural Products by :
Download or read book Progress Toward the Total Synthesis of the Epoxyquinoid Family of Natural Products written by and published by . This book was released on 2007 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Enyne metathesis is a powerful C-C bond forming reaction that combines an alkene and an alkyne and forms a conjugated 1,3-diene. The scope of enyne metathesis was expanded by combining various alkynes with vinyl ethers. Typically vinyl ethers are poor metathesis substrates, but a method was developed for the synthesis of dienol ethers utilizing ruthenium carbenes. The products of these reactions were subjected to [4+2] cycloaddition conditions to give substituted cyclohexene rings. The epoxyquinoid family is a highly targeted series of natural products. A general method for the synthesis of the core structure of these natural products has been explored. An enyne cross metathesis/ring closing metathesis step was designed as the key reaction to this synthesis. A Darzen's condensation between a chiral [alpha]-alkoxy aldehyde and a chloroacyl oxazolidinone was successfully employed to join two fragments of the molecule as well as to install an epoxide. A highly diastereoselective cuprate addition set the stereochemistry of the first stereogenic center. The early intermediates were prepared via easily scalable organic syntheses procedures including utilizing a carbohydrate as the source of chirality. Ring closing enyne metathesis to form the epoxyquinoid core was evaluated in two epimeric series.
