sequential oxygen and carbenoid insertions into diverse alkyl- and arylboronates. It offers a distinct entry to a wide range of boron-substituted ethers. The utilities of this method are demonstrated in the preparation of various functional ethers, the asymmetric synthesis of an acetyl-CoA-carboxylase inhibitor, and the programmable construction of polyethers.
