Some scientific research about (S)-Propane-1,2-diol

This compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,(S)-Propane-1,2-diol,4254-15-3,its application will become more common.

4254-15-3 A common heterocyclic compound, 4254-15-3,(S)-Propane-1,2-diol, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.

Zu einer Loesung von 1.50 g (19.7 mmol) S-1, 2-Propandiol in 15 ml Dichlormethan werden 2.75 ml (19.7 mmol) Triethylamin, 0. 10 g (0. 8 MMOL) 4-N, N-Dimethylaminopyridin und 2. 97 G (19.7 mmol) tert. -Butyldimethylsilylchlorid gegeben. Die Reaktionsmischung wird fuer 16 h bei Raumtemperatur geruehrt. Anschliessend wird mit Dichlormethan verduennt und je zweimal mit Wasser, gesaettigter Ammoniumchlorid-Loesung und gesaettigter Natriumhydrogencarbonat-Loesung gewaschen. Die organische Phase wird ueber Natriumsulfat getrocknet und im Vakuum vom Loesungsmittel befreit. Der Rueckstand wird ohne weitere Reinigung in der naechsten Stufe eingesetzt. Ausbeute : 2.55 g, 80% Reinheit (54% d. Th.) GC/MS (Methode 6) : RT = 2.62 min., M/Z = 191 (M+H)+., 4254-15-3

This compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,(S)-Propane-1,2-diol,4254-15-3,its application will become more common.
