Ring closing metathesis of enamines derived from isoquinolines and beta-car
boline occurs in DCM at room temperature in good yields. The products of ri
ng closing metathesis bear close structural relationships to many alkaloida
l natural products and are obtained in yields that bear approximate inverse
proportionality to the calculated basicity of the enamine starting materia
