Agents de dédoublement. 2. Synthèse d'aryluréthanes de l'acide (S)-lactique et leur utilisation dans le dédoublement de bases racémiques
摘要:
Reaction of the arylisocyanates 2a-c with ethyl (S)-(-)-lactate, followed by careful saponification, afforded the corresponding chiral acids (S)-(-)-4a-c. The latter were successfully used for the resolution of various racemic bases belonging to both the ephedrine and alpha-aryl ethylamine series.
