Copper(I)- and Copper(II)-catalyzed Diels-Alder Additions of α-Substituted Acrylonitrile to Furan. The Synthesis of 7-Oxa-bicyclohept-5-en-2-one
The difficult Diels-Alder additions of α-acetoxy- and α-chloroacrylonitrile to furan can be run at 20-35 deg and atmospheric pressure in the presence of CuCl, Cu(BF4)*6 H2O, Cu(OOCCH3)2*H2O or cupric tartrate*3 H2O.Under kinetic control, the exo-carbonitr
