The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: (((4R,5R)-2,2-Dimethyl-1,3-dioxolane-4,5-diyl)bis(methylene))bis(diphenylphosphine)( cas:32305-98-9 ) is researched.Name: (((4R,5R)-2,2-Dimethyl-1,3-dioxolane-4,5-diyl)bis(methylene))bis(diphenylphosphine).He, Zhenxiu; Zhou, Yongyun; Sun, Weiqing; Fan, Ruifeng; Shen, Guoli; Fan, Baomin published the article 《Asymmetric ring opening reaction of oxabenzonorbornadienes with phenols promoted by rhodium/zinc complexes》 about this compound( cas:32305-98-9 ) in Youji Huaxue. Keywords: asym ring opening oxabenzonorbornadiene phenol rhodium zinc catalyst. Let’s learn more about this compound (cas:32305-98-9).
The complex of [Rh (COD)Cl]2 and (2R,4R)-(+)-2,4-bis(diphenylphosphino)pentane was used as an effective catalyst for the asym. ring opening reaction of oxabenzonorbornadienes with various phenols by employing ZnI2 as the activator. Under the optimized reaction conditions, high enantioselectivities with good yields could be obtained from a wide scope of oxabenzonorbornadienes and phenols.
This literature about this compound(32305-98-9)Name: (((4R,5R)-2,2-Dimethyl-1,3-dioxolane-4,5-diyl)bis(methylene))bis(diphenylphosphine)has given us a lot of inspiration, and I hope that the research on this compound((((4R,5R)-2,2-Dimethyl-1,3-dioxolane-4,5-diyl)bis(methylene))bis(diphenylphosphine)) can be further advanced. Maybe we can get more compounds in a similar way.
