The preparation of 1,4‐dicarbonyl, 4‐oxo nitrile, furan, and pyrrole monomers

Abstract
Treatment of cyclopentadiene‐blocked acrolein with α,β‐unsaturated ketones, esters, and nitriles in the presence of a thiazoliurn salt under basic conditions led to a simple method for the preparation of acetonylmethyl Vinyl ketone, 2‐carboxymethylethyl vinyl ketone, and 2‐cyanoethyl vinyl ketone. In addition, the cyclopentadiene‐blocked acetonylmethyl vinyl Ketone was converted to heterocyclic furan and pyrrole monomers.
