With (iso)quinoline as the nucleophile and carbonyl compounds, such as aldehydes, ketones, and N-substituted isatins as electrophiles, the reaction afforded oxazino (iso)quinoline derivatives and the reaction proceeded via 1,4-dipolar intermediates. Interestingly, when the nucleophilic trigger used is pyridine, the reaction furnished indolin-2-one derivatives, and it is probable that the reaction proceeds via a pyridylidene intermediate.</p>10aarynes - multicomponent reaction - oxindoles - pyridines - quinolines1 aBhunia, Anup1 aBiju, Akkattu, T.  uhttps://library.ncl.res.in/content/employing-arynes-transition-metal-free-n-heterocycles-initiated-multicomponent-reactions
