A CONVENIENT METHOD FOR OPTICAL RESOLUTIONS VIA DIASTEREOISOMERIC SALT FORMATION

Acs, M.,Fogassy, E.,Faigl, F.

, p. 2465 - 2470 (2007/10/02)

With the advantage of the method using two immiscible solvents and half-equivalent amount of the resolving agent, higher optical purity can be obtained than in cases of any other resolution via diastereoisomeric salt formation, besides it is a faster procedure for resolution of a new racemate as well.
