With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.4254-15-3,(S)-Propane-1,2-diol,as a common compound, the synthetic route is as follows.
(S)-Methylethylene Bis(methylsulfonate), CAS 270577-16-7, Compound A Scheme 1,was prepared from (S)-(+)-1,2-propanediol (CAS 4254-15-3, Sigma Aldrich Chemical Company) and methane sulfonyl chloride (CAS 124-63-O, Sigma Aldrich Chemical Company) according to the procedure of T. Harada, T. Mai, T. Tuyet, and A. Oku, Organic Letters (2000), 2(9), 1319-1322.
As the paragraph descriping shows that 4254-15-3 is playing an increasingly important role.
