标 题 :Enantioselective synthesis of L-(-)-4- boronophenylalanine (L-BPA)
发明人：SAMSEL EDWARD G
权利人:US ENERGY
摘要:A method of making substantially pure L-BPA is disclosed. The method includes the steps of reacting 4-bromobenzaldehyde with ethylene glycol to form 4-bromobenzaldehyde ethylene glycol acetal, sequentially reacting 4-bromobenzaldehyde ethyleneglycol acetal with Mg to produce the Grignard reagent and thereafter reacting with tributyl borate and then converting to an acid environment to form 4-boronobenzaldehyde, reacting 4-boronobenzaldehyde with diethanol amine to form 4-boronobenzaldehyde diethanolamine ester, condensing the 4-boronobenzaldehyde diethanolamine ester with 2-phenyl-2-oxazolin-5-one to form an azlactone, reacting the azlactone with an alkali metal hydroxide to form z-α-benzoylamino-4-boronocinnamic acid, asymmetrically hydrogenating the z-α-benzoylamino-4-boronocinnamic acid in the presence of a catalyst of a cheltate complex of rhodium (I) with chiral bisphosphines to form L-(+)-N-benzoyl-4-boronophenylalanine, and thereafter acidifying the L-(+)-N-benzoyl-4-boronophenylalanine in an organic medium to produce L-BPA.

标 题 :Hydroaminomethylation of olefins
发明人：BRIGGS JOHN R; WHITEKER GREGORY T; KLOSIN JERZY
权利人:DOW GLOBAL TECHNOLOGIES INC
摘要:The present invention relates to a method comprising the step of contacting under hydroaminomethylation conditions, an olefin, an amine, a rhodium-phosphorous ligand, and synthesis gas (syngas). In particular, it has been discovered that, under some circumstances, a neutral rhodium-monodentate phosphite ligand is prescribed. The invention provides a simple way of making, in high yields and regiospecificity, a variety of products, including pharmacologically active products such as ibutilide, terfenadine, and fexofenadine, and derivatives thereof.
