Synthetic Route of 4254-15-3, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.4254-15-3, Name is (S)-Propane-1,2-diol, molecular formula is C3H8O2. In a Article£¬once mentioned of 4254-15-3
The regioselective and stereospecific substitution of unsymmetrical 1,2-diols using the 1,3,2lambda5-dioxaphospholane methodology
Stereo specific tosylate (-OTs) or azide (N3-) substitution at the C-4 stereocenter of a monosubstituted 1,3,2lambda5-dioxaphospholane (the equivalent of the C-2 stereocenter in an unsymmetrical 1,2-diol) is readily achieved by treatment with either P-toluenesulfonic acid (P-TsOH) in tetrahydrofuran solvent or P-TsOH/sodium azide in acetonitrile solvent, respectively.
