Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 4144-22-3, is researched, SMILESS is O=C(C=C1)N(C(C)(C)C)C1=O, Molecular C8H11NO2Journal, Tetrahedron Letters called Synthesis of rotaxanes consisting of crown ether wheel and sec-ammonium axle under basic condition, Author is Nakazono, Kazuko; Oku, Tomoya; Takata, Toshikazu, the main research direction is rotaxane preparation crown ether wheel sec ammonium axle.Reference of 1-(tert-Butyl)-1H-pyrrole-2,5-dione.
A novel synthetic method of [2]rotaxane by end-capping of pseudorotaxane via conjugate addition of thiol to N-substituted maleimide C=C bond under basic condition was developed. Several [2]rotaxanes were obtained in good yields.
Compound(4144-22-3)Reference of 1-(tert-Butyl)-1H-pyrrole-2,5-dione received a lot of attention, and I have introduced some compounds in other articles, similar to this compound(1-(tert-Butyl)-1H-pyrrole-2,5-dione), if you are interested, you can check out my other related articles.
