Studies toward total synthesis of non-aromatic Erythrina alkaloids. (1) Synthesis and isomerization of unsaturated bicyclic δ-lactones

As a model of the C/D ring system of erythroidines, bicyclic unsaturated δ-lactones were synthesized in a regio-selective manner, and their isomerization reactions in the presence of acid, base (DBU, 1,8-diazabicyclo-[5.4.0]undec-7-ene), and NaOH were stu
