标 题:Synthesis of nanofibers of polyaniline and substituted derivatives
发明人：EPSTEIN ARTHUR J; CHIOU NAN-RONG
权利人:OHIO STATE UNIVERISTY
摘要:Novel, simple methods are presented directed to the synthesis of nanofibers of polyaniline and substituted derivatives. The production of these fibers is achieved via various methods by controlling the concentration of aniline monomer or substituted aniline derivatives or an oxidant in the reaction medium and maintaining said concentration at a level much lower than conventional polyaniline synthesis methods. Methods are disclosed relating to the use of a permeable membrane to control the release of a monomer and/or oxidant as well as a bulk polymerization method.

标题 :Synthesis of polyaniline or derivatives thereof
发明人：ALAMRY KHALID A; KHAN AJAHAR; ASIRI ABDULLAH MOHAMED
权利人:UNIV KING ABDULAZIZ
摘要:Provided are synthesis methods of polymerizing aniline or derivatives thereof. The production of polyaniline or polyaniline derivatives is controlled by the type of oxidant added in the reaction medium. The methods include the step of using a safe and environmentally friendly carbomethyl cellulose (CMC) or modified CMC as an oxidant in the polymerization reaction to produce polyaniline or aniline derivatives. Synthesis methods of producing O-CMC and O-CMC-S oxidants are also provided herein.

摘要:The present invention relates to the development of novel compounds of chromeno [4,3-b] quinolone derivatives. It particularly relates to the development of novel compounds of thiochromeno [4,3-b] quinolone derivatives for the treatment of coronary artery diseases, dyslipidemia, and metabolic syndrome. The present invention also relates to the first synthesis of Silicotungstic -catalyzed Aza-Diels-Alder-reactions (ADAR) with s-prenyl derivatives of α-tetralone, 4-chromanone and Thiochroman-4-one and various substituted amines to deliver cycloadducts in good yield and excellent diastereoselectivity under mild reaction conditions. The invention further relates to the method for the treatment of coronary artery diseases, dyslipidemia, and metabolic syndrome by using synthesized compounds of thiochromeno [4,3-b] quinolone derivatives. The present invention provides the use of Silicotungstic acid as Lewis acid for Aza-Diels-Alder-reactions to get a mixture of diastereomers are the first examples. In addition to its efficiency, simplicity, and mild reaction conditions, the catalyst is very cheap and only a small amount (10 mol%) is needed. Intramolecular cyclization was carried out very conveniently as a one-pot reaction starting from the S-prenyl chromene-3-carbaldehyde and arylamines without isolation of the intermediate imines.

发明人：WHITE WILLIAM A
权利人:LILLY CO ELI
摘要:A simple process for the preparation of beta -aminostyrenes proceeds from anilines by successively diazotizing, reacting with a vinyl ester, and reacting with a secondary amine without purification of the intermediate products. The compounds are reactive enamines useful in organic synthesis.
