Hsu, Day-Shin; Liang, Suz-Ping published the artcile< NHC-Mediated Synthesis of Tricyclic Spirocarbocycles via an Intramolecular Stetter Reaction of Cyclic Enal-Enones>, Safety of (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is tricyclic spirocarbocycle preparation; cyclic enal enone intramol Stetter reaction nitrogen heterocyclic carbene.
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.
Journal of Organic Chemistry published new progress about Diketones Role: SPN (Synthetic Preparation), PREP (Preparation). 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Safety of (9Z,12Z)-Methyl octadeca-9,12-dienoate.
