Li, Sha; Xu, Jiayu; Luo, Xian; Yang, Wenhan; Yao, Changsheng published the artcile< Efficient N-heterocyclic carbene-catalyzed cascade synthesis of functionalized naphthopyranone>, Name: (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is heterocyclic carbene catalyst naphthopyranone cascade reaction preparation.
An efficient N-heterocyclic carbene(NHC)-catalyzed “”Michael-Michael-Lactonization”” cascade process involving chalcone derivatives and α-bromoenals for the syntheses of functionalized naphthopyranones was disclosed. This approach was qualified with good yields, readily available starting materials and mild reaction conditions.
Youji Huaxue published new progress about Lactonization. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Name: (9Z,12Z)-Methyl octadeca-9,12-dienoate.
