Zhong, Jiaxin; He, Haibing; Gao, Shuanhu published an article in 2019, the title of the article was Exploration of 1,3-dipolar cycloaddition reactions to construct the core skeleton of Calyciphylline A-type alkaloids.Formula: C7H10O3 And the article contains the following content:
Nitrone induced 1,3-dipolar [3+2] cycloadditions were studied to construct the core structure of Calyciphylline A-type Daphniphyllum alkaloids. This approach is capable of installing the cis-hydroindole A-C ring as well as the spiro-A-C-E ring with the all-carbon quaternary centers at C-5 and C-8, and has been successfully used in the total synthesis of himalensine A. It also lays the foundation for the synthesis of challenging Calyciphylline A-type alkaloids, such as daphniyunnine A. The experimental process involved the reaction of Methyl 2-cyclopentanonecarboxylate(cas: 10472-24-9).Formula: C7H10O3
The Article related to calyciphylline a daphniphyllum alkaloid preparation nitrone dipolar cycloaddition, Alkaloids: Alkaloids Containing One Nitrogen Atom In A Ring and other aspects.Formula: C7H10O3
