Synthesis, modelling and NK1 antagonist evaluation of a non-rigid cyclopropane-containing analogue of CP-99,994
摘要:
A non-rigid cyclopropane-containing diamine analogue of CP-99,994 was synthesised and was found to have only moderate NK1 receptor binding affinity. Molecular dynamics calculations of the conformational space of the former compound gave good correlation between observed activity and a recently published pharmacophore model, lending predictive value to the latter.

Cyclopropanone acetal 2a undergoes the one-pot Strecker synthesis under sonication to provide the amino nitrile 8, which after hydrolysis and catalytic hydrogenolysis, gives 1-aminocyclopropanecar☐ylic acid (ACC, 1) in good overall yield.

A new synthesis of trans-1,2-diaminocyclobutane 1 is described, in which the key feature is the novel stereoselective borane-induced reductive ring-expansion reaction of the cyclopropane-iminonitrile 2 to give the cyclobutane 4. This latter intermediate was also used to prepare a trans-fused rigid analogue of moclobemide.
