4254-15-3, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. (S)-Propane-1,2-diol, cas is 4254-15-3,the chiral-oxygen-ligands compound, it is a common compound, a new synthetic route is introduced below.
The four (4) step reaction sequence starting from 103-1 and 103-2 (prepared as shown from S-(+)-1,2-propanediol (103-0)) provided Boc-T103a in a very good overall yield of 85%. The alternatively protected analogue Ddz-T103a was prepared using the same procedure with an overall yield of 55% [1.4 g Ddz(2RMe)opy18 was obtained starting from 1 g (5.8 mmol) of 103-1]. Synthesis of the Boc-T103b stereoisomer proceeds similarly, but starting from R-(-)-1,2-propanediol.TLC: Rf: 0.3 (100% EtOAc)
The chemical industry reduces the impact on the environment during synthesis,4254-15-3,(S)-Propane-1,2-diol,I believe this compound will play a more active role in future production and life.
