Pyroglutamic acid salts of t-butylamino-2,3-dihydroxypropane
Process for resolving enantiomers of 1-t-butylamino-2,3-dihydroxypropane using a pyroglutamic acid or a tartaric acid as resolving agent. The enantiomers of 1-t-butylamino-2,3-dihydroxypropane are useful in preparing β-adrenergic blocking agents.
