TREN, tris- -amine

Chapman et al. [131] reported the synthesis of poly(ethylene oxide) (PEO) supported dendritic f-BOC-poly(a, c-L-lysines). These dendritic polymers termed as hydramphiphiles formed foams possessing good temporal stability in aqueous solution. Scrimin et al. [132] synthesized a three-directional polypeptide having uses in membrane permeability modulation. Decapeptide fragments were linked to TREN [tris(2-aminoethyl)amine] core.

System 11 consists of two tetramine ligating compartments, tren (tris(2-ami-noethyl)amine)) and cyclam (1,4,8,11-tetraazacyclotetradecane), that display different coordinating tendencies toward metals and are separated by a 1,4-xylyl spacer.14...

Macrobicyclic cascade cryptands have also been prepared such as the series of bis(tren) derived (tren = tris(2-aminoethyl) amine, see Section 4.4.3) compounds 5.9. The di-nickel(II) and di-copper(II) complexes of the cages with various spacers all bind a metal cation into each tren unit. These metal...

Tritopic cyclen- and isocyclam- (isocyclam = 1,4,7,11-tetraazacyclotetradecane) based ligands 121 and 122 were prepared according to Scheme 17. Tosylated tren derivative (tren = tris(2-aminoethyl)amine) was cyclized under Richman-Atkins conditions to give the fully tosylated amines in relatively high yield considering the [1+3] reaction <2002JOC9107>.
