A series of 2-aminoalkylethers prepared as potentialantiarrhythmicagents is described. The present compounds are mixed sodium and potassium ion channel blockers and exhibit antiarrhythmic activity in a rat model of ischemia-induced arrhythmias. Structure-activity studies led to the identification of three compounds 5, 18, and 26, which were selected based on their particular in vivo electrophysiological
the DoI reaction of zinc? Kinetic/thermodynamic competitive experiments and DFT calculations were performed to clarify the regioselectivity and reactionmechanism/pathways of lithium chloride‐promoted directedzincinsertion into bromobenzenes. The results strongly suggest that the LiCl‐containing “push–pull form” transition state (TSb) is formed at an early stage, thus accelerating the reaction rate
