The present invention relates to the field of organic synthesis and more particularly to a new process for the optical resolution of a precursor of sclareolide. This process includes the reaction of [(1RS,2RS,4aSR,8aSR)-2-hydroxy-2,5,5,8a-tetramethyldecahydronaphthalen-1-yl]acetic acid, or an alkaline salt thereof, with an enantiomer of the 2-(methylamino)-1-phenyl-1-propanol, or an ammonium salt thereof respectively, which is used as resolving agent.
本发明涉及有机合成领域,更具体地说,它涉及一种新工艺,用于斯卡雷内酯前体的光学解析。该工艺包括[(1RS,2RS,4aSR,8aSR)-2-羟基-2,5,5,8a-四甲基十氢萘-1-基]乙酸或其碱性盐分别与 2-(甲基氨基)-1-苯基-1-丙醇的对映体或其铵盐反应,后者用作解析剂。
