title: [Lactones. 28. EPC-synthesis, structure and pharmacology of "lactonized" and "lactamized" analogues of acetylcholine].
abstract: The enantiopure gamma-aminomethyl-gamma-butyrolactones (S)- and (R)-4a-d represent constrained analogues of acetylcholine, which were synthesized from D- or L-glutamic acid following two different routes. In addition, the corresponding lactames (S)- and (R)-10 were prepared by enantioselective synthesis. Only moderate activity was found at acetylcholine sites at the guinea pig atrium.
