On January 17, 2020, Hsu, Day-Shin; Liang, Suz-Ping published an article.Category: esters-buliding-blocks The title of the article was NHC-Mediated Synthesis of Tricyclic Spirocarbocycles via an Intramolecular Stetter Reaction of Cyclic Enal-Enones. And the article contained the following:
A general and efficient method for the synthesis of tricyclic spirocarbocycles is described. Various cyclic enal-enones were reacted with an N-heterocyclic carbene and an intramol. Stetter reaction proceeded smoothly to give various tricyclic spiro-1,4-diketones in 31-72% yields. The ring size of the spiro compounds can be easily controlled using different cyclic enals and enones, or by altering the length of the carbon tether. The experimental process involved the reaction of Methyl 2-cyclopentanonecarboxylate(cas: 10472-24-9).Category: esters-buliding-blocks
