Imidazo[1,2-a]pyridines: Orally Active Positive Allosteric Modulators of the Metabotropic Glutamate 2 Receptor
摘要:
Advanced leads of an imidazopyridine series of positive allosteric modulators of the metabotropic glutamate 2 (mGlu2) receptor are reported. The optimization of in vitro ADMET and in vivo pharmacokinetic properties led to the identification of 27o. With good potency and selectivity for the mGlu2 receptor, 270 affected sleep-wake architecture in rats after oral treatment, which we have previously shown to be indicative of mGlu2 receptor-mediated central activity.

An efficient strategy for N/O-(deutero)alkylation of indoles and phenols with alkoxides/alcohols as the alkylation reagents is described. The consecutive detosylation/alkylation transformations feature mild reaction conditions, high ipso-selectivity, and good functional group tolerance (>50 examples). A one-pot selective N-alkylation of unprotected indoles with alcohols and TsCl is also realized. The
