A direct Cross-Dehydrogenative-Coupling (CDC) between benzyl ethers and simple ketones was developed without using any metal catalyst. By using DDQ, various benzyl ethers and simples ketones were coupled together directly to form beta-alkoxyl ketones efficiently. A mechanism in which the DDQ serves the double roles of an oxidizing agent and an organomediator was proposed.
Oxidative Alkylation of Cyclic
Benzyl Ethers with Malonates and Ketones Using Oxygen as the Terminal
Oxidant
A simple oxidative alkylation of cyclic benzylethers with malonatesand ketones was developed using a mixture of Cu(OTf) 2 ,InCl 3 , and NHPI as catalyst under an atmospheric pressureof oxygen.
