A new application about [1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium(II)

We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 72287-26-4, and how the biochemistry of the body works.Electric Literature of 72287-26-4

Electric Literature of 72287-26-4, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.72287-26-4, Name is [1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium(II), molecular formula is C34H28Cl2FeP2Pd. In a Article，once mentioned of 72287-26-4

Enantiomerically pure L-BPA (4-borono-L-phenylalanine) was synthesized from L-tyrosine or 4-iodo-L-phenylalanine derivatives using the palladium- catalyzed cross-coupling reaction of pinacolborane (2,3-dimethyl-2,3- butanediolatoboron). Cbz-Tyr(Nf)-OBzl (2b) underwent the cross-coupling reaction with pinacolborane (1) in the presence of [PdCl2(PPh3)2] catalyst to give N-benzyloxycarbonyl-4-(2,3-dimethyl-2,3-butanediolatoboryl)-L- phenylalanine benzyl ester (3a) in 58% yield. The reaction of the 4-iodo-L- phenylalanine derivatives, such as N-benzyloxycarbonyl-4-iodo-L-phenylalanine benzyl ester (2c), N,N-dibenzyl-4-iodo-L-phenylalanine benzyl ester (2d), (4S)-3-benzyloxycarbonyl-4-(4-iodobenzyl)-5-oxazolidinone (2e), and (4S)-3-t- butyloxycarbonyl-4-(4-iodobenzyl)-5-oxazolidinone (2f), with 1 proceeded very smoothly in the presence of [PdCl2(dppf)] catalyst, giving N- benzyloxycarbonyl-4-(2,3-dimethyl-2,3-butanediolatoboryl)-L-phenylalanine benzyl ester (3a), N,N-dibenzyl-4-(2,3-dimethyl-2,3-butanediolatoboryl)-L- phenylalanine benzyl ester (3b), (4S)-3-benzyloxycarbonyl-4-[4-(2,3-dimethyl- 2,3-butanediolatoboryl)benzyl]-5-oxazolidinone (3c), and (4S)-3- butyloxycarbonyl-4-[4(2,3-dimethyl-2,3-butanediolatoboryl)benzyl]-5- oxazolidinone (3d), respectively, in high yields. Deprotection of 3a-d gave enantiomerically pure L-BPA in high total yields.
