The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: (2S)-(+)-3-Chloropropane-1,2-diol( cas:60827-45-4 ) is researched.Quality Control of (2S)-(+)-3-Chloropropane-1,2-diol.Kwon, Mi-Ae; Kim, Geon-Joong published the article 《Synthesis of polymeric salen complexes and application in the enantioselective hydrolytic kinetic resolution of epoxides as catalysts》 about this compound( cas:60827-45-4 ) in Catalysis Today. Keywords: polymeric chiral salen cobalt complex preparation epoxide resolution catalyst; terminal epoxide hydrolytic kinetic resolution chiral polymeric salen cobalt; epoxide enantioselective preparation; chiral diol enantioselective preparation. Let’s learn more about this compound (cas:60827-45-4).
The polymeric (salen) Co(III) catalysts containing various counter anions have been synthesized, and the asym. catalytic activities of these newly synthesized polymer-type salen complexes were investigated in the HKR of terminal epoxides. The polymeric chiral salen Co(III) complexes catalyze the hydrolysis of epichlorohydrin, 1,2-epoxybutane, 1,2-epoxyhexane and epoxystyrene with very high enantioselectivities under mild conditions. The catalysts could be recovered and reused several times without further treatment after reaction, showing no loss of activity and enantioselectivity.
This literature about this compound(60827-45-4)Quality Control of (2S)-(+)-3-Chloropropane-1,2-diolhas given us a lot of inspiration, and I hope that the research on this compound((2S)-(+)-3-Chloropropane-1,2-diol) can be further advanced. Maybe we can get more compounds in a similar way.
