Samarium diiodide catalyzes a one pot procedure allowing to perform sequentially the Mukaiyama-Michael addition of a ketene silyl acetal on a cyclic α,β-unsaturated ketone, followed by a Mukaiyama aldol reaction of an aldehyde. The adducts are isolated as silyl ethers in good yields and in most cases with high diastereoselectivity.
