摘　　要：Cyclic dithioacetals of α,α-dioxo (estcr) ketene 3 were reacted with butanone to afford the Michael adducts 4, catalyZed by metal Na. This process provides a new method for the Synthesis of ring-compouds in goob yield under mild conditions.Cyclic dithioacetals of α,α-dioxo (estcr) ketene 3 were reacted with butanone to afford the Michael adducts 4, catalyZed by metal Na.
