The syntheses of paullone (1a) and three paullone derivatives, including a sulfur analogue (2a), a tricyclic derivative (2b), and a ring-enlarged variant (2c), are described, Pd-catalyzed intramolecular Heck reaction being the key step. The kinase-inhibitory properties of the novel paulloneanalogues were investigated.
