Disclosed herein are novel motuporamine compounds that act as anti-metastatic agents with low toxicity and high anti-migration activity. The non-toxic, anti-metastatic agents may be given to patients with potential or actual metastatic cancers, such as pancreatic cancers, alone in combination with known and/or new therapies to help block the growth and spread of tumor(s)..

Single-crystal X-ray diffraction analysis of one of the analogues 20 showed that in the solid state its 16-membered macrocyclic amine fragment adopted the [4444] quadrangular conformation predicted by calculations to be the lowest energy conformation for the corresponding cycloalkane, cyclohexadecane. These data along with literature X-ray data and conformational analysis for derivatives of azacyclotridecane

Tertiary acyclic allyl amines and tertiary cyclic α-vinyl amines undergo conjugate additions to acetylenic sulfones to produce zwitterion intermediates, followed by 3-aza-Cope rearrangements. In the case of cyclic α-vinyl amines, the process results in ring-expansion, providing a novel route to 9- to 17-membered cyclic amines. The Hammett plot for the reaction of 8b with 2a−2f shows ρ = +1.19, which
