Abstract:
The article describes the synthesis of acetylene amino alcohols based on secondary acetylene alcohol and amino compounds containing a hydroxyl group, the results of scientific research and their analysis to study the influence of factors such as temperature and catalyst on the yield of the product in the process. In the course of the work, a new type of acetylene amino alcohol was obtained with high efficiency as a result of the condensation reaction of ethanolamine (or diethanolamine) with hex-1-yn- 3-ol mediated by formaldehyde. Optimal conditions for carrying out synthesis processes have be

Abstract:
Abstract Regiodivergent synthesis of allenes and acetylenes was established in the reduction of propargylic phosphates. The palladium(0)-catalyzed reduction of secondary propargylic phosphates with samarium(II) iodide gave allenes or acetylenes by tuning proton sources (tert-butyl alcohol or dimethyl L-tartrate).

Abstract:
This review article gives a survey of the principal biosynthetic pathways that lead to the most important common fatty acids and their derivatives occurring in foods and feeds. Fatty acids are further subdivided to saturated fatty acids and unsaturated fatty acids. This review is focused on the less common fatty acids including geometrical and positional isomers of unsaturated fatty acids, acetylenic fatty acids, branched-chain fatty acids, alicyclic fatty acids, epoxy fatty acids, hydroxy fatty acids, and oxo fatty acids. A survey is further given on the biosynthesis of the aliphatic very-lon

Abstract:
Activated manganese dioxide (MnO2) reliably oxidizes acetylenic, allylic, and benzylic alcohols to aldehydes and ketones. Saturated primary and secondary alcohols are also oxidized, albeit more slowly. The two main concerns are the activity of the manganese dioxide and the slow filtration of salts after the reaction. Activated MnO2 is available commercially or may be prepared. To a solution of 15.3 g (37.5 mmol) of the alcohol in 150 mL of hexanes was added 60 g of activated MnO2. The reaction mixture was stirred at 22 °C overnight and filtered, and the solid residue was washed with 30% EtOAc

Abstract:
Reaction with an enantiomerically-pure epoxide is an efficient way to construct a molecule incorporating an enantiomerically-pure oxygenated stereogenic center. The Jacobsen hydrolytic resolution has made such enantiomerically-pure epoxides readily available from the corresponding racemates. Christopher Jones and Marcus Weck of the Georgia Institute of Technology have now (J. Am. Chem. Soc. 2007, 129, 1105) developed an oligomeric salen complex that effects the enantioselective hydrolysis at remarkably low catalyst loading. Any such approach depends on monitoring the progress of the hydrolysis,
