Begum, Zubeda; Sannabe, Haruka; Seki, Chigusa; Okuyama, Yuko; Kwon, Eunsang; Uwai, Koji; Tokiwa, Michio; Tokiwa, Suguru; Takeshita, Mitsuhiro; Nakano, Hiroto published an article in 2021, the title of the article was Simple primary β-amino alcohols as organocatalysts for the asymmetric Michael addition of β-keto esters to nitroalkenes.Reference of Methyl 2-cyclopentanonecarboxylate And the article contains the following content:
Simple primary β-amino alcs. acted as an efficient organocatalysts in the asym. Michael addition of β-keto esters with nitroalkenes which afforded highly pure chiral Michael adducts. Also, both enantiomers of the adducts were obtained, depending on the specific catalyst used and reaction temperature The experimental process involved the reaction of Methyl 2-cyclopentanonecarboxylate(cas: 10472-24-9).Reference of Methyl 2-cyclopentanonecarboxylate
The Article related to keto ester nitroalkene amino alc catalyst enantioselective diastereoselective michael, nitroalkanyl keto ester preparation, Alicyclic Compounds: Cyclopentanes, Including Fulvenes and Fulvalenes and other aspects.Reference of Methyl 2-cyclopentanonecarboxylate
