Synthesis and calcium antagonistic activity of a series of diethyl benzofuryl, benzothienyl and benzogammapyronyl benzylphosphonates
摘要:
In this work we present about 15 original heterocyclic diethyl benzylphosphonate analogues of fostedil, in which we have varied the nature of the heterocycle, the substituents or the phosphonic group, or even the position of this latter. Three diethyl 4-(2-benzofuryl) benzyl phosphonates exhibited slightly higher calcium antagonism than the control. Solely substitution with a fluorine atom was able to maintain activity, whereas the other modifications always decreased it.

range of 2-arylbenzo[b]furans are synthesized through domino intermolecular C(aryl)–C(alkynyl) bond formation followed by intramolecular C(alkynyl)–O bond forming cyclization via copper(II)-catalyzed coupling of o-iodophenols and aryl terminal acetylenes. This method requires neither expensive palladium catalyst nor oxophilic phosphine ligands, can tolerate different functional groups. The methodology
