According to a study from Sherbrooke, Canada, "Both macrolactams cyclo-[NH-CH2-C C-CH2-C(Me)(2)-CO](n) (n = 3 and n = 2) have been synthesized and crystallized. They have respectively one intramolecular hydrogen bond and no such bond."
"Both macrocycles self-assemble as parallel supramolecular walls with or without inclusion of solvent between them. The units of the former (n = 3) are held together by NH center dot center dot center dot pi/NH center dot center dot center dot OC interactions, whereas they are glued by a very dense network of classical parallel-oriented hydrogen bonds, involving all the amides of the rings, in the latter (n = 2). In that case, the ...
