Diastereomeric Salt Resolution Based Synthesis of LY503430, an AMPA (α-Amino-3-hydroxy-5-methyl-4-isoxazolepropionic Acid) Potentiator
摘要:
This article describes the development and optimization of chemical reactions and subsequent preparation of the API LY503430 under cGMPs to fund first human dose (FHD) clinical evaluation as a potential therapeutic agent for Parkinson's disease. Reasons and rationale are presented for changes in solvents and reagents. One of the major developments presented here is the replacement of a chiral chromatography with a diastereomeric salt resolution. This article also discusses a preferred orientation issue with LY503430 which complicated the XRPD analysis.
The present invention provides certain monofluoroalkyl derivatives useful for potentiating glutamate receptor function in a mammal and therefore, useful for treating a wide variety of conditions, such as psychiatric and neurological disorders.
N,N-Dialkyl-β-amino alcohols were enantiospecifically and regioselectively rearranged by using N,N-diethylaminosulfur trifluoride (DAST) to give optically active β-fluoroamines in excellent yields and enantiomeric excesses. This rearrangement was applied to the enantioselectivesynthesis of LY503430, a potential therapeutic agent for Parkinson’s disease.
