A short synthesis of rigid 2-alkylthio-2,2-diaryl substituted acetic acids
摘要:
The metalation of rigid diphenyl methane derivatives has been studied, aiming at the synthesis of 2-alkylthio-2,2-diaryl substituted acetic acids esters, a class of compounds with a potential antimuscarinic activity. Mixed metal bases have shown to be necessary in order to obtain the desired compounds with a good regiocontrol. (C) 1998 Elsevier Science Ltd. All rights reserved.
