Reactions of triene-conjugated nitrile ylides: a route to 1,4-dihydro-1,4-prop-1′-enoisoquinolines from systems with α,β aromatic and γ,δ; ε,ζ olefinic unsaturation

Abstract

Triene-conjugated nitrile ylides with α,β aromatic and γ,δ; ε,ζ olefinic unsaturation undergo intramolecular cyclisation and rearrangement to give 1,4-dihydro-1,4-prop-1′-enoisoquinolines.
