摘要:The present invention is directed to methods for oxidizing internal olefins to ketones. In various embodiments, each method comprising contacting an organic substrate, having an initial internal olefin, with a mixture of (a) a biscationic palladium salt; and (b) an oxidizing agent; dissolved or dispersed in a solvent system to form a reaction mixture, said solvent system comprising at least one C 2-6 carbon nitrile and optionally at least one secondary alkyl amide, said method conducted under conditions sufficient to convert at least 50 mol % of the initial internal olefin to a ketone, said ketone positioned on a carbon of the initial internal olefin. The transformation occurs at room temperature and shows wide substrate scope. Applications to the oxidation of seed oil derivatives and a bioactive natural product are described.

摘要:N- 4-(Cyanoethylthiomethyl)-2-thiazolyl!guanidine, is prepared by (a) mixing 1,3-dihaloacetone and 2-imino-4-thiobiuret in a suitable polar organic solvent at initial temperatures of about -10° to about 25° C., and agitating the mixture at about -10° to about 60° C. for at least about 1 hour; (b) heating the resultant mixture at about 40° to about 60° C. for at least about 0.5 hour; (c) mixing with the mixture from (b), thiourea and then water at about 40° to about 60° C. for a period of at least about 1 hour; (d) removing liquid polar solvent from the mixture of (c); and (e) mixing with the mixture from (d), 3-halopropionitrile and water-soluble alcohol, ether, or ether-alcohol, followed by aqueous alkali metal hydroxide while maintaining the temperature at below about 20° C., to form N- 4-(cyanoethylthiomethyl)-2-thiazolyl!guanidine. The process avoids isolating and purifying any of the intermediates, and can be conducted in the same vessel, as a 'one-pot' synthesis.

摘要:Embodiments herein relate to apparatus and systems for phenolic and ketone synthesis and methods regarding the same. In an embodiment, a method of producing phenolics and ketones is included. The method can specifically include forming a reaction mixture comprising nanocrystalline cellulose (NCC) and water. The method can also include contacting the reaction mixture with a metal oxide catalyst at a temperature of 350 degrees Celsius or higher and a pressure of at least about 3200 psi to form a reaction product mixture. The reaction product mixture can include at least about 20 wt. % phenolics and at least about 10 wt. % ketones as a percentage of the total mass of nanocrystalline cellulose (NCC). Other embodiments are also included herein.

权利人:WANG GUIJUN; MANGUNURU HARI P R; OLD DOMINION UNIV RES FOUND
摘要:Described herein are the one-pot synthesis and characterization of a library of low molecular weight peptoid compounds that are able to form gels at room temperature. The compounds are synthesized from biologically-based starting materials, are biocompatible, and are resistant to degradation by proteases and peptidases. The compounds and gels synthesized therefrom can be used in such applications as tissue engineering, drug delivery, separation of biomolecules, and stimulus-responsive advanced materials

摘要:Novel tricyclic-bis-enone derivatives (TBEs) as well as the process for the preparation of such TBEs are provided. Also provided are methods for prevention and/or treatment of cancer, Alzheimer's disease, Parkinson's disease, multiple sclerosis, amyotropic lateral sclerosis, rheumatoid arthritis, inflammatory bowel disease, and all other diseases whose pathogenesis is believed to involve excessive production of either nitric oxide (NO) or prostaglandins or the overexpression of iNOS or COX-2 genes or gene products. Further, methods for the synthesis of the TBE compounds of the invention utilize cheap commercially available reagents and are highly cost effective and amenable to scale-up. Additional high efficiency synthetic methods that utilize novel intermediates as well as the synthesis of these intermediates are also provided. Furthermore, the invention also provides methods for designing novel and water-soluble TBEs.
