On April 2, 2021, Liao, Zhehui; Zhang, Jiantao; Cao, Tongxiang; Zhu, Shifa published an article.Quality Control of Methyl 2-cyclopentanonecarboxylate The title of the article was Copper-Catalyzed Asymmetric Synthesis of Bicyclo[3.n.1]alkenones. And the article contained the following:

A series of highly strained bicyclo[3.n.1]alkenones such as I (R = Me, Et, i-Pr) have been successfully constructed in good to excellent enantioselectivities and moderate to good yields by copper-catalyzed formal [3+3] cycloaddition reaction of 2-oxocycloalkanecarboxylates and aryl vinyl ketones or arylethenyl vinyl ketones via nonracemic oxoalkyl-substituted oxocycloalkanecarboxylates such as II (R = Me, Et, i-Pr). The cycloadducts were selectively converted into various valuable bicyclic ring systems holding considerable potential for the construction of natural and bioactive compounds containing a [3.n.1] moiety. The experimental process involved the reaction of Methyl 2-cyclopentanonecarboxylate(cas: 10472-24-9).Quality Control of Methyl 2-cyclopentanonecarboxylate
