Butane-1,4-diamine

Tetrakis(picolyl)propane-l,3-diamine and its butane-1,4-diamine analogue each contain two terdentate chelating units and can thus provide the groups L on both iron atoms, giving further bridging (see also Section 5.4.S.4.3 below). ...

A fourth possibility is the generation of H202 via oxidation of putrescine (butane-1,4-diamine 2.56). This reaction is catalyzed by copper amine oxidase (E.C. 1.4.3.6). Copper amine oxidases are homodimers in which each unit contains a copper ion and a 1,3,5-trihydroxyphenylalanine quinine co-factor. In plants copper amine oxidases generally oxidize putrescine to 4-aminobutanal (2.57). This latter compound undergoes spontaneous cyclization to A1 pyrroline (2.58), ammonia, and H202, as shown in Figure 2-12 (Medda et al., 1995).

As part of the synthetic studies directed towards the natural product caracasanamide, the oxaze-pine (54) (Scheme 10) was obtained in low yield during the acylation of excess butane-1,4-diamine by ( )-3,4-dimethoxycinnamoyl chloride, the oxazepine being formed by cyclization of the mono-acylated product (53) diacylation of the diamine provided the major product <92JCS(Pl)3l79>. 

Tetsuka and co-workers [15] showed that the of copolymers prepared by two-step polycondensation reactions of adipate, butane-1,4-diamine and linear diol homopolyesters were higher than those of polyesters consisting of the same ester units, and tended to increase with an increase in amide content of copolymers produced from adipate, butane-1,4-diol, and butane-1,4-diamine had especially high thermal stabilities compared to polytetramethylene adipate. They had of more than 200 °C. 

Template condensation of LI 74 with formaldehyde and a primary diamine (ethane-1,2-diamine, butane-1,4-diamine and/or l,4-bis(aminomethyl)-benzene affords bis(macrocyclic) nickel(II) complexes [Ni2(L178)] (Eq. 2.105), which can be reduced to corresponding dinickel(I) species, which are extremely sensitive to oxygen and moisture [212]. 

Ligand product L656 was assembled from 2,6-diformylpyridine (2,6-dfp) and butane-1,4-diamine on barium(II) as template [30]. Transmetallation with man-ganese(II) in the presence of an excess of thiocyanate yielded the tetrathio-cyanato derivative [Mn2(L656)(NCS)4], which can easily be converted into [Mn2(L656)(NCS)3(OCH3)j on crystallisation from methanol. X-Ray diffraction confirmed the latter complex to be macrocyclic and binuclear [30]. 

Pyridoxal phosphate-catalyzed decarboxylation (ornithine decarboxylase, EC 4.1.1.17) yields butane-1,4-diamine (putrescine) directly. Arginine (Arg, R) first undergoes pyridoxal phosphate-catalyzed decarboxylation (arginine [Arg, R] decarboxylase, EC 4.1.1.19) to agmatine and then hydrolytic loss of urea (agmatinase, EC 3.5.3.11) to produce the same diamine. Ornithine and arginine (Arg, R) are members... 

Tripodal tris-aldehyde ligand syntones, which have been prepared in [94] using Vilsmeier-Haack-type formylation of the corresponding tris-pyrroles by Scheme 2.82, gave the covalent capsules 124 and 125, the derivatives of ethylene-1,2- and butan-1,4-diamines, respectively. These macrobicyclic hgands encapsulate parent diamines during the template condensation with...
