The enantioselective synthesis of these homochiral amides from racemic precursors is challenging using existing chemistries. The synthesis of the corresponding chiral carboxylic acid, required for a traditional amide coupling, can also involve multi-step synthesis using toxic and expensive transition-metals,...
Synthesis and characterization of aliphatic segmented poly(ether amide urethane)s through a non-isocyanate route Two nylon-6 oligomers with polymerization degrees (DP orn) of 6.82 and 4.52 terminated with H2N- and HO-groups (H2N–PAn–OHs) were prepared from caprolact... S Li,J Zhao,Z ...
In this way we have accessed reversible amide bond formation that allows crystalline order to develop. This strategy permits the direct synthesis of practically irreversible ordered amide networks that are stable thermally and under both strong acidic and basic hydrolytic conditions....
