Synthesis of some poly(4‐alkyl‐4‐azaheptamethylene‐D‐glucaramides)

Six 4‐alkyl‐4‐azaheptane‐1,7‐diamines, characterized as their solid bis(D ‐gluconamides), were prepared in a two‐step synthesis: bis(cyanoethylation) of the primary alkylamines (C₈–C₁₈, even‐numbered) followed by an efficient lithium aluminum hydride reduction of the resulting bisnitriles. The azadiamines were then used as monomers in condensation polymerizations with methyl D ‐glucarate 1,4‐lactone in a methanol solution, yielding polyhydroxypolyaminopolyamides isolated directly as white solids with varying hydrophobic/hydrophilic character. © 2000 John Wiley & Sons, Inc.
