MACROCYCLIC POLY AMINES

MACROCYCLIC POLY AMINES, 58, 86, 90 MACROLIDES, 58, 98 Magnesium, bromo phenyl, 58, 138 Magnesium methyl carbonate, 56, 121 Maleic acid, methyl ester, 56, 63 Manganese, tricarbonyl[(l,2,3,4,5-7))-l-carboxy-2,4-cyclopentadien 1 yl], ... [Pg.187]

Macrocyclic derivatives are of considerable importance in biological areas and as complexing agents, particularly for metals. Macrocyclic examples are given in MACROLIDES FROM CYCLIZATION OF w-BROMOCARBOXYLIC ACIDS 11-HYDROXYUNDECANOIC LACTONE and MACROCYCLIC POLY AMINES 1,4,7,10,13,16-HEX AAZ ACYCLOOCT ADE-... [Pg.234]

Macrocyclic poly amines as biological cation and anion complexones — an application to calculi dissolution. E. Kimura, Top. Curr. Chem., 1985,128,113 (85). [Pg.7327]

Receptors for anions vary widely, and are in many instances either the same or modified versions of the ligands that bind transition metal ions [5-20], For example, poly amine macrocycles can bind transition metal ions, while poly ammonium macrocycles bind anions. In many instances the same ligand can bind either a transition metal ion [21-24] or an anion [25-29],... [Pg.173]

To synthesize macrocycles in good yields, the reactions of di(3-bromobenzene)polyamines 12 with corresponding poly amines 2 were run in the presence of a double amount amount of catalyst (16 mol%), in dilute dioxane solutions, and in the majority of cases corresponding cyclodimers were formed in reasonable to good yields (up to 44%). [Pg.126]

The problem of isolation and purification of bis(polyamine)-substituted pyridines 21 was found to be quite serious and we decided to use them in situ in the synthesis of eyelodimers, producing them from 1 equiv. of dibromide and 4 equiv. of polyamine to minimize possible excess of polyamines which would lead to macrocycles and not to cyclodimers. Following the method (A), eyelodimers 22a,fj,l,m were synthesized by the reaction of bis(halopyridinyl)-substituted poly amines 17a and 19a,fj with polyamines 2a,fj (Scheme 10). [Pg.129]

This review presents the syntheses of different analogs of sucrose. Transformations of this di-saccharide at the terminal positions (Cl, or C6, or C6 ) provide modified sucroses such as amines, uronic acids, thiols, or phosphorus derivatives. Preparation of so-called higher sucroses i.e. derivatives in which the terminal positions are elongated by a poly-hydroxylated carbon chain is also reviewed. Special attention is directed to the synthesis and properties of macrocyclic derivatives crown- and aza-crown ethers with sucrose scaffold. Such macrocyclic receptors exhibit interesting complexing properties towards chiral ammonium salts. [Pg.260]

Analogously, the aspartie protease inhibitor 228 (Figure 11.17, site of reaction and reducing reagent indieated) was constructed via an intramolecular reductive amination. In addition, multiple reductive amina-tions can be applied to assemble molecules such as the symmetrical G-quadruplex macrocyclic ligand BOQl (229) and antiprotozoal poly-azamacrocycles such as 230. For the latter, an iron (II) complex was employed as an intermediate to assist with the ring closure. [Pg.461]
