Alcohol-ester separation by recrystallization |
| abstract |
A process is disclosed for the separation of an enantiomerically enriched 1-tosyloxy-2-acyloxy-3-butene and an enantiomerically enriched 1-tosyloxy-2-hydroxy-3-butene from a first mixture containing both compounds. The process includes the steps of: n (a) forming a solution of the mixture in an organic solvent; n (b) bringing the solution formed in (a) to a temperature wherein most of the enantiomerically enriched 1-tosyloxy-2-hydroxy-3-butene precipates, leaving in solution most of the enantiomerically enriched 1-tosyloxy-2-acyloxy-3-butene; and n (c) separating the precipitate formed in (b) from the solution. |
