Method for producing 2-methylspiro(1,3-Oxathiolane-5,3')quinuclidine
摘要
<p>A method for producing 2-methylspiro(1,3-oxathiolane-5,3')quinuclidine (MSOQ), which comprises isomerizing 3-hydroxy-3-mercaptomethylquinuclidine (QHT) or a salt thereof in the presence of a catalyst of a tin halides, to produce cisform 2-MSOQ or a salt thereof.</p>
