Abstract: Enamino ketones 5 react with b-oxo alkenes 4, without solvent, at room temperature or under focused microwaves to give new, highly functionalized cyclohexenes 7 and 9 in good yields. A mechanism is proposed. The procedure is mild, efficient, economical and environmentally benign. Key words: solvent-free reactions, enamino ketones, cyclohexenes, b-oxo alkenes
