A Facile Transition Metal-Free Ionic Liquid [BMIM]OH Mediated Regio- and Stereoselective Hydrocarboxylation of Alkynylnitriles

We report an efficient and straight forward access to nitrile substituted enol esters via ionic liquid [BMIM]OH mediated hydrocarboxylation of alkynylnitriles under mild conditions. This atom economical transition metal-free protocol gives an easy access to a variety of such enol esters with excellent regio and Z-stereoselectivity. Reusability of [BMIM]OH without losing of significant amount of yield is another noticeable feature of this article.

Heterocyclic Imines and Amines. Part 19. Isoquinoline and Other Products from α,o-Dicyanostilbene and Basic Reagents

α,o-Dicyanostilbene (1) was cleaved by hydrazine or hydroxylamine under mildly acid conditions to o-cyanobenzyl cyanide (2) and benzaldehyde, isolated as derivatives.Sodamide with compound (1) gave 1-amino-4-cyano-3-phenylisoquinoline: alkoxides similarly gave the 1-alkoxy compounds, the presumed intermediate 3,4-dihydroisoquinoline from the methoxide reaction being isolated and separately dehydrogenated.Acid hydrolysis of the 1-ethoxy compound gave the known 4-cyano-3-phenylisoquinolin-1(2H)-one.With the anion of o-cyanobenzyl cyanide, compound (1) gave a 1-amino-4-cyano-3-(2-substituted phenyl)isoquinoline, which was oxidised to 1-amino-4-cyano-3-(2-carboxyphenyl)isoquinoline.The latter lost water at 210 deg C to give yellow 12-cyano-5-iminoisoindoloisoquinolin-7(5H)-one, closely related to known compounds.
