Available in PDF, EPUB and Kindle. Book excerpt: Our research focuses on the total synthesis of naturally occurring highly oxidized and densely functionalized carbon skeletons. The generation of dearomatized intermediates and o-quinone methides enable the rapid manipulation and derivatization of aromatic cores. o-Quinone methides in particular undergo a variety of reactions, but in the presence of enol ethers cycloaddition reactions predominate, which enable access to complex spiroketal derivatives. The use of this technology enables the generation of spiroketals in a kinetic fashion, not possible through traditional thermodynamic ketalizations. Herein, we will overview our studies towards finding an appropriate o-quinone methide precursor and demonstrate the application of this methodology towards the total synthesis of paecilospirone, a marine natural product whose unique chroman spiroketal core had not previously been encountered in nature prior to its isolation.

Available in PDF, EPUB and Kindle. Book excerpt: Organic synthesis, with the invention of new synthetic strategies and technologies, has evolved from largely empirical approaches for the preparation of relatively simple molecules to sophisticated strategies for the construction of molecules with considerable structural and functional complexity. Organic synthesis is employed to synthesize the natural product and its analogs for the discovery of new drugs. The development of new synthetic methodologies in the course of total synthesis is imperative for the efficient synthesis of drug candidates. Apart from the practical applications, the pursuit of efficient syntheses of complex natural products is both gratifying and truly enjoyable. Chapter One describes the development of annulation reaction for the construction of five-, six- and seven- membered rings. Chapter Two describes a direct approach to the synthesis of methyllycaconitine, a representative of the aconitine alkaloids. The numbering of the compounds, schemes and references are independent in each section.

Available in PDF, EPUB and Kindle. Book excerpt: "This thesis describes the first, enantioselective total synthesis of the marine natural product paecilospirone (1). Paecilospirone is a polyketide derived metabolite isolated from the marine fungus Paecilomyces sp. collected off the coast of Yap Island, Federated States of Micronesia. Structural assignment following anticancer bioassay subsequently revealed a novel spiro[chroman-2,1(3H)- isobenzofuran] core where an -hydroxyl group occupies the unusual axial position of the sixmembered tetrahydropyran ring. An efficient and flexible strategy was developed to provide access to the [5,6]-bisbenzannulated spiroacetal in a convergent manner. Three key fragments, bromide 162, aldehyde 120 and ketone 92, were synthesised using readily available starting materials. In particular, ketone 92 was obtained from the chiral pool, thus allowing the facile incorporation of enantioselectivity into the synthesis. The fragments were successfully coupled together using an aryllithiation addition and a diasteresoselective, anti-boron aldol reaction. Initial attempts at the late stage spiroacetalisation reaction focused on the acid-mediated cyclisation of MOM-protected ketone 112. However, upon spirocyclisation, 113 readily underwent elimination to afford the corresponding dehydrated products. The problem was exacerbated by the axial orientation of the oxygenated group positioned to the spirocentre and anti to a vicinal hydrogen atom, thus a revision in protecting group strategy was enforced whereby access to the spiroacetal core was envisioned using pH neutral conditions. Attention therefore focused on the model study of a dihydroxyketone equivalent (123) in which the alcohol groups were protected as allyl ethers. Accordingly, treatment of 123 with Pd(PPh3)4 in the presence of a range of silane addictives successfully furnished the desired spiroacetal 124, clearly demonstrating the synthetic utility of this method for the preparation of sensitive spiroacetal systems. Subjection of bis-allyl ketone 166 to the established reaction conditions ultimately led to the completion of the total synthesis of paecilospirone 1"--Abstract.

This book was released on 2021-06-18 with total page 609 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fungi are an understudied, biotechnologically valuable group of organisms. Due to their immense range of habitats, and the consequent need to compete against a diverse array of other fungi, bacteria, and animals, fungi have developed numerous survival mechanisms. However, besides their major basic positive role in the cycling of minerals, organic matter and mobilizing insoluble nutrients, fungi have other beneficial impacts: they are considered good sources of food and active agents for a number of industrial processes involving fermentation mechanisms as in the bread, wine and beer industry. A number of fungi also produce biologically important metabolites such as enzymes, vitamins, antibiotics and several products of important pharmaceutical use; still others are involved in the production of single cell proteins. The economic value of these marked positive activities has been estimated as approximating to trillions of US dollars. The unique attributes of fungi thus herald great promise for their application in biotechnology and industry. Since ancient Egyptians mentioned in their medical prescriptions how they can use green molds in curing wounds as the obvious historical uses of penicillin, fungi can be grown with relative ease, making production at scale viable. The search for fungal biodiversity, and the construction of a living fungi collection, both have incredible economic potential in locating organisms with novel industrial uses that will lead to novel products. Fungi have provided the world with penicillin, lovastatin, and other globally significant medicines, and they remain an untapped resource with enormous industrial potential. Volume 1 of Industrially Important Fungi for Sustainable Development provides an overview to understanding fungal diversity from diverse habitats and their industrial application for future sustainability. It encompasses current advanced knowledge of fungal communities and their potential biotechnological applications in industry and allied sectors. The book will be useful to scientists, researchers, and students of microbiology, biotechnology, agriculture, molecular biology, and environmental biology.
