  Insertion of Allenes into the Pd–C Bond of Ortho-Palladated Primary Arylamines of Biological Relevance: Phenethylamine, Phentermine, (l)-Phenylalanine Methyl Ester, and (l)-Tryptophan Methyl Ester. Synthesis of Tetrahydro-3-benzazepines and Their Salts

  摘要：

  The previously reported ortho-metalated complexes [Pd(C,N-ArCH2CRR'NH2-2)(mu-X)](2) derived from phenethylamine (Ar = C6H4, R = R' = H, X = Cl, Br), phentermine (Ar = C6H4, R = R' = Me, X = Cl), (L)-phenylalanine methyl ester (Ar = C6H4, R = H, R' = CO2Me, X = Cl, Br)), and (L)-tryptophan methyl ester (Ar = C8H5N, R = H, R' = CO2Me, X = Cl) react with various allenes to give (1) the corresponding eta(3)-allyl complexes derived from the insertion of one molecule of the allene into the Pd-C bond, the formation of which has been studied by DFT using a model complex, or (2) Pd(0) and the tetrahydro-3-benzazepinium salts, resulting from the decomposition of the above mentioned eta(3)-allyl complexes, containing an exocyclic double bond, which, subsequently, react with a base to afford the corresponding benzazepines. The regiochemistry of these decomposition reactions has been studied and compared wit:a that described for similar processes involving five-membered palladacycles. The crystal structures of the salts of some benzazepines and one isoquinoline, derived from a five-membered palladacycle, have been determined by X-ray diffraction studies.

  Orthometalation of Primary Amines. 4.¹ Orthopalladation of Primary Benzylamines and (2-Phenylethyl)amine

  摘要：

  By the refluxing of an acetonitrile solution of [Pd(OAc)(2)](3) and primary amines 4-XC(6)H(4)CH(2)NH(2) (F, Cl, NO2, OMe), 3,5-X(2)C(6)H(3)CH(2)NH(2) (X = OMe), or PhCH(2)CH(2)NH(2) (Pd:amine = 1:1) and subsequent addition of excess NaBr, the corresponding orthometalated complexes [Pd{C6H3(CH2NH2)-2,X-5}(mu-Br)](2), [Pd{C6H3(CH2NH2)-2,(OMe)(2)-4,6}(mu-Br)](2), or [Pd{C6H3(CH2NH2)-2}(mu-Br)](2) are obtained. Alternatively, the hydrochloride of 4-XC(6)H(4)CH(2)NH(2) (X = F, NO2) can also be used to prepare the corresponding [Pd{C6H3(CH2NH2)-2,X-5}(mu-Cl)](2) complexes. These results show that primary benzylamines can be orthometalated even if the substituents are electron-withdrawing groups and that 2-(phenyl)ethylamine can be orthometalated in spite of the six-membered ring that it forms. These reactions occur via intermediate complexes [Pd(OAc)(2)L(2)], which react with [Pd(OAc)(2)](3) to give the dimeric species [Pd(OAc)(mu-OAc)L](2) (L = amine), from which in turn the orthometalated complexes are formed. Each of these steps has been studied, and both types of intermediates have been isolated for all the amines. PPh(3) reacts with the orthometalated complexes to give the corresponding products of the bridge splitting. The crystal structures of [Pd(OAc)(mu-OAc)L](2) (L = 4-O2NC6H4CH2NH2) and [Pd{C6H4(CH2CH2NH2)-2}Br(PPh(3))] have been determined by X-ray diffraction.

  A new method for high-yield cyclopalladation of primary and secondary amines involving the corresponding ammonium triflates, instead of the amines generally employed, is reported. The method is applied for the synthesis of Buchwald-type precatalysts [Pd(C,N-C6H4CH2CH(R′)NHR-2)X(phosphine)] that can be easily prepared by reaction of Pd(OAc)2, 1 equiv of the ammonium triflate [PhCH2CH(R′)NH2R]OTf, and
