In contrast to its acyclic analogue P(NMe2)3 (1), which in benzene at room temperature reacts with two aryl aldehyde molecules bearing electron-withdrawing groups to give the corresponding diaryl epoxide as an isomeric mixture (trans/cis ratios: 72/28-51/49), P(MeNCH2CH2)3N (2a) under the same reaction conditions is found to be a highly selective reagent that provides epoxides with trans/cis ratios
question. Herein, we present synthesis and optimization of a novel series of 1,2-bis(aryl)ethane-1,2-diamines with selectivity for Kv1.5 over other potassium ion channels. The effective refractory period in the right atrium (RAERP) in a rabbit PD model was investigated for a selection of potent and selective compounds with balanced DMPK properties. The most advanced compound (10) showed nanomolar potency
