Samarium diiodide-induced couplings of carbonyl compounds with methoxyallene leading to 4-hydroxy 1-enol ethers.
A surprising samarium diiodide-induced coupling reaction of carbonyl compounds with methoxyallene provided 4-hydroxy 1-enol ethers, which are versatile synthetic building blocks. In this coupling reaction, methoxyallene serves as an acrolein equivalent, which cannot directly be employed. [reaction: see text]
