    The antifungal and antimicrobial properties of fatty acids have been known for centuries. Compared to saturated fatty acids, unsaturated fatty acids with double and/or triple bonds are, in general, more potent against fungal pathogens ().The representative unsaturated fatty acid with a single double bond at C, undecylenic acid (UDA), is still on the market as a cost-effective antifungal.

Bohlmann (Author),Cited by: According to Ferdinand Bohlmann, the first naturally occurring acetylenic compound, dehydromatricaria ester, was isolated from an Artemisia species in In the nearly two centuries that have followed, well over a thousand naturally occurring acetylenes have been discovered and reported.

Naturally occurring acetylenes. London, New York, Academic Press, The hypothesis that the triple bond of natural acetylenes is formed by a dehydrogenation and that these compounds are derived from common fatty acids by various oxidation processes is confirmed by the demonstration that [ C]oleic acid is converted by Tricholoma grammopodium into [ C]octadecenynoic acid and into [ C]decen-4,6,8-triynol, and by the presence in Cited by: This article is cited by 7 publications.

urally occurring acetylenes, which now represent a new large group of natural products. Since the biosynthesis ofacety-lenes is also elaborated to a wide extent, the arrangement of this book is mainly along biogenetic lines.

However,synthe-sis and chemotaxonomic viewpoints are also covered in detail. [The SCI® indicates. Publisher Summary. The alkylation of metallated acetylenes and allenes involves the reaction of metallated acetylenes and allenes with alkyl halides in the usual organic solvents Et 2 O and THF and in liquid ammonia.

As compared to several other types of synthetic intermediates, 1-alkynylides, RC≡CM (M═Li, Na, K), show a moderate reactivity towards alkyl halides. This book provides a comprehensive and up-to-date compilation of the chemistry and applications of phosphorus ylides in organic synthesis. The ylides are discussed as reagents in the synthesis of a broad range of substances, amongst them olefins, acetylenes, cyclic and heterocyclic compounds, in such naturally occurring compounds as pheromones.

Naturally occurring mosquito larvicidal acetylenes 1 and 2, and analogues 3 and 4, each containing either a 1,3-butadiynyl or a 1,3,5-hexatriynyl moiety, are synthesized via a Fritsch−Buttenberg−Wiechell rearrangement.

The alkylidene carbenoid intermediate results from lithium−halogen exchange of a suitable dibromoolefin precursor, and the rearrangement is accomplished under mild conditions. Search books Search.

The extract was chromatographed on Si gel column with petrol-Et^O. TLC on 1 mm thick layers of Si gel GF 2 54 (20 x 20 cm plates) developed with the same eluants was used to isolate the various acetylenes. 3 and 4 were identified by UV, IR and TLC comparison with authentic samples. Alkynes in Cycloadditions presents a comprehensive summary of the literature on methods for the synthesis of ring systems from acetylenes for academic researchers working in the fields of organic synthesis, physical organic chemistry, organometallic chemistry, catalysis, materials science, nanomaterials and biochemistry.

ISBN  Natural polyacetylenes are compounds whose structures contain two or more triple bonds. More than different acetylenes and biogenetically related substances have been identified in plants of the Asteraceae family.

The various tribes of this family are characterized by individual sets of acetylene metabolites, allowing these compounds to be regarded as important chemotaxonomic. Book Reviewed in this article: An Introduction to Plant Physiology.

Naturally occurring aquatic acetylenes are of particular interest since many of them display important biological activities and possess antitumor, antibacterial, antimicrobial, antifungal, phototoxic, HIV inhibitory, and immunosuppressive properties. NOARC stands for Naturally-Occurring Acetylenes and Related Compounds (also National Oceans and Applications Research Center and 2 more) What is the abbreviation for Naturally-Occurring Acetylenes and Related Compounds?.

The purpose of this Handbook is to sensitize the reader to this problem and to provide a systematic overview of the most important naturally occurring food toxicants. The Handbook should be of interest to anybody who is concerned with nutritive and health aspects of food.Naturally Occurring Quinones aims to discuss where quinones, a major group of organic compounds that are considered as pigments, can be found in nature.

The book also explains its significance in chemistry and other related fields. The text also mentions the different plant and animal origins of these compounds.
