Synthesis of furanyl and oxazolyl N-substituted piperidine and imidazoline salts as potential agonists of M1 muscarinic receptors
(Chemical Equation Presented) Furanyl and oxazolyl N-substituted imidazoline salts were prepared by reacting furanyl and oxazolyl esters with ethylenediamine and trimethyl aluminum, followed by the addition of methyl iodide or hydrogen chloride. The piperidinium salts were prepared by treating furanyl and oxazolyl chlorides with piperidine base, followed by the addition of methyl iodide or hydrogen chloride.
Synthesis of oxazolyl-substituted morpholinium salts
Morpholinium salts coupled to oxazolyl moieties have been synthesized via nucleophilic substitution of a series of oxazolyl chlorides with morpholine. The oxazole moieties were first synthesized and then coupled with morpholine. The corresponding hydrochloride and methyl iodide salts were obtained, purified, characterized and then tested for muscarinic receptor binding affinity. Biological test results from MDS Pharma Services revealed no significant muscarinic receptor affinity.
