The method includes reacting a nitrophenyl compound with N,N-dimethylformamide diethyl acetal.
专利号:US-7973171-B2 优先权日:2005-06-13 标题:Process for synthesis of dialkoxyorganoboranes 发明人:BURKHARDT ELIZABETH; ATKINS WILLIAM 权利人:BURKHARDT ELIZABETH; ATKINS WILLIAM 摘要:The invention relates to a process for the synthesis of dialkoxyorganoboranes, in particular to a process for the synthesis of dialkoxyorganoboranes by an ester exchange reaction. Moreover, the invention relates to a process for the synthesis of organo-oxazaborolidine catalysts (organo-CBS) and of trialkylboroxins. Furthermore, the invention relates to methods of using dialkoxyorganoboranes for the preparation of organo-CBS catalysts and in Suzuki-type coupling reactions.
专利号:US-8084007-B2 优先权日:2004-01-30 标题 :Methods of synthesis of isotropically enriched borohydride and methods of synthesis of isotropically enriched boranes 发明人:SPIELVOGEL BERNARD; COOK KEVIN S 权利人:SPIELVOGEL BERNARD; COOK KEVIN S; SEMEQUIP INC 摘要:The invention provides new methods for the synthesis of isotopically enriched metal borohydrides, metal tetrahydroundecaborate salts, and decaborane from isotopically enriched 10 B-boric acid or 11 B-boric acid. The invention is particularly useful for synthesis of isotopically enriched sodium or lithium borohydride, MB 11 H 14 (where M is Li, Na, K, or alkylammonium), and decaborane.
专利号:US-11999757-B2 优先权日:2017-11-01 标 题:Synthesis of boronate ester derivatives and uses thereof 发明人:BOYER SERGE HENRI; HECKER SCOTT J; VERZIJL GERARDUS K M; HERMSEN PETRUS J 权利人:MELINTA SUBSIDIARY CORP 摘要:Disclosed herein are methods for the preparation of boronate derivatives in the synthesis of antimicrobial compounds and uses thereof. Disclosed herein includes method of making a compound of Formula (B) by reducing the ketone group of the keto-ester compound of Formula (A), and the reduction can be performed using a Ruthenium based catalyst system or using an alcohol dehydrogenase bioreduction system.

Additionally disclosed is the synthesis of a novel amorphous, nanostructured bimetallic compound of dysprosium erbium borate trihydrate used in this formulation.
专利号:US-5679864-A 优先权日:1995-11-03 标题:Process for the synthesis of curcumin-related compounds 发明人:KRACKOV MARK HARRY; BELLIS HAROLD EDWARD 权利人:GENE PRINT INC 摘要:The invention is directed to a process for the synthesis of curcumin and curcumin-related compounds by reacting the enol form of a 2,4-diketone with a monocarbocyclic aldehyde in the presence of an organic amine catalyst. The reactants are dissolved in a highly polar, aprotic organic solvent. The curcumin-related product is recovered in crystalline form by precipitation from the reaction mass and solvent recrystallization.
