A method for resolving enantiomers of a compound containing the structure of the formula:
1
wherein R
4
or R
5
may contain one or more asymmetric centers, by mixing a racemic mixture of enantiomers of a compound, containing the structure of said formula; in a solvent, with a resolving compound having a defined stereospecificity, to form a solution and with said resolving agent being capable of binding with at least one but not all of said enantiomers to form a precipitate, containing said at least one of said enantiomers in stereospecific form and collecting either the precipitate and purifying it or collecting the solution with contained other of said enantiomers and recrystallizing the enantiomer contained in said solution.
一种用于分离具有公式1结构的化合物的对映体的方法,其中R4或R5可能包含一个或多个不对称中心,通过将具有公式所述化合物的对映体的混合物与具有定义的立体特异性的分离剂在溶剂中混合,形成溶液,并且所述分离剂能够与至少一个但不是全部的对映体结合形成沉淀,其中所述沉淀包含所述至少一个对映体的立体特异性形式,并收集沉淀并纯化它或收集溶液和所含的其他对映体并重结晶所含的对映体。
