On September 13, 2017, Sargent, Brendon T.; Alexanian, Erik J. published an article.Recommanded Product: (R)-Methyl 3-hydroxybutanoate The title of the article was Cobalt-Catalyzed Carbonylative Cross-Coupling of Alkyl Tosylates and Dienes: Stereospecific Synthesis of Dienones at Low Pressure. And the article contained the following:
Nonracemic dienones such as I were prepared diastereoselectively and enantiospecifically in 38-82% yields and in 93:7-98.5:1.5 enantiospecificities by coupling of secondary alkyl tosylates such as II with 1,3-dienes such as (E)-PhCH:CHCH:CH2 in the presence of KCo(CO)4 and 2,2,6,6-tetramethylpiperidine in tert-amyl alc. under 2 atm. of CO pressure. The experimental process involved the reaction of (R)-Methyl 3-hydroxybutanoate(cas: 3976-69-0).Recommanded Product: (R)-Methyl 3-hydroxybutanoate
The Article related to dienone nonracemic diastereoselective preparation, cobalt catalyst stereoselective carbonylation coupling secondary alkyl tosylate diene, enantiospecific carbonylative cross coupling secondary alkyl tosylate diene and other aspects.Recommanded Product: (R)-Methyl 3-hydroxybutanoate
