| titleOfInvention | A process for the separation of macrocyclic diastereomers |
| abstract | A process for the separation of the two diastereomers (3S,7R) and (3S,7S)-3,4,5,6,7,8,9,10,11,12-decahydro-7,14,16-trihydroxy-3-methyl- 1H -2-benzoxacyclotetradecin-1-one (α- and β-zeranol), of formulae Ia and Ib:n starting from the mixture thereof, which contains 50-60% diastereomer Ia, by means of crystallization from acetonitrile containing 0.2-2% water, under controlled cooling conditions, to obtain compound Ia ( α-zeranol) with a diastereomeric purity (titre) higher than 98.5%. |
