    摘要: Optically active salts are disclosed of the formula (I): ##STR1## wherein Ac represents an acyl group, R.sup.1 hydrogen or methyl, R.sup.2 and R.sup.3 identical or different substitutes, preferably methyl. The salts can be obtained from the corresponding optically active carbonic acid and DL-3-cyano-2-hydroxypropyl trimethylammonium hydroxide. The diastereomeric salt pairs are easily split from one another and separated again, so that the process is suited for producing optically active 3-cyano-2-hydroxypropyl trimethylammonium salts.
