And the article contained the following:
A facile and convenient reaction of o-alkynylisocyanobenzenes with various active-methylene compounds, including 1,3-diesters, 1,3-diketones,β-keto esters, and β-keto amides, under Bronsted basic conditions, had been developed. Di-Et malonate reacted smoothly with a collection of o-alkynylisocyanobenzenes to provide the corresponding 2-quinolin-2-yl malonates in excellent yields. Acetylacetone gave a mixture of quinolin-4-yl and quinolin-2-yl derivatives Acetoacetate esters and acetoacetyl amide derivative initially gave 2-quinolin-2-yl adducts that underwent partial deacetylation under the reaction conditions. The experimental process involved the reaction of 3-Acetyldihydrofuran-2(3H)-one(cas: 517-23-7).Name: 3-Acetyldihydrofuran-2(3H)-one
The Article related to quinoline preparation, alkynylisocyanobenzene dicarbonyl compound cyclization, Heterocyclic Compounds (One Hetero Atom): Quinolines and Isoquinolines and other aspects.Name: 3-Acetyldihydrofuran-2(3H)-one
