An expeditious and atom-economic synthesis of lead-like, medicinally important 4,5-dihydropyrazolo[1,5-a]pyrazin-6-ones
摘要:
We have developed an expeditious and atom-economic synthesis of lead-like, privileged 4,5-dihydropyrazolo[1,5-a]pyrazin-6-ones, which is based on Sonogashira coupling and a two-step condensation with hydrazine hydrate leading to two ring-forming events, with full control over the two elements of diversity present.

A series of milnacipran analogs were synthesized and studied as monoamine transporter inhibitors, and several potent compounds with moderate lipophilicity were identified from the 1S, 2R-isomers. Thus, 15l exhibited IC50 values of 1.7 nM at NET and 25 nM at SERT, which were, respectively, 20- and 13-fold more potent than 1S, 2R-milnacipran 1-II. (C) 2008 Elsevier Ltd. All rights reserved.
