Abstract
Inventia se refera la un procedeu de obtinere a S-(-)-3-(3-tertbutilamino-2-hidroxipropoxi)-4-(N-morfolino)-1,2,5-tiadiazolului [S-(-)Timolol baza] prin scindarea (R,S)-Timololului prin diestereoizomeri de tip monoesteri Timolol-acid (R,R(-)O,O-tartric disubstituit. Scindarea are loc în doua etape: obtinerea esterului diastereoizomer si hidroliza alacalina sau acida a acestuia. Puritatea optica 99...100%.
