Abstract
Wynalazek opisuje sposób wytwarzania diastereomerycznie czystego p-toluenosulfinianu O-(1R,2S,5R)-mentylowego o absolutnej konfiguracji (S), który polega na tym, że roztwór racemicznego chlorku p-toluenosulfinylowego i enancjomerycznie czystego (1S, 2R, 5S)-mentolu pozostawia się w temperaturze pokojowej na 14 dni, po czym utworzony diastereomerycznie czysty, lewoskrętny (-)-(S)-p-toluenosulfinian O-(1R, 2S, 5R)-mentylowy izoluje się usuwając jedynie wydzielony w reakcji chlorowodór.The invention describes a process for the production of diastereomerically pure O- (1R, 2S, 5R) -mentyl p-toluenesulfinate having absolute (S) configuration, which consists in that a solution of racemic p-toluenesulfinyl chloride and enantiomerically pure (1S, 2R, 5S) - menthol is left to stand at room temperature for 14 days, after which the diastereomerically pure, levorotatory O- (1R, 2S, 5R) -mentyl (-) - (S) -p-toluenesulfinate formed is isolated by removing only the hydrogen chloride evolved from the reaction.
