p-Quinol ethers are valuable synthons in synthetic organic chemistry. MOBs 1a-1i can be converted to p-quinol ethers 2a-2i in a highly efficient manner via 1,3-methoxy migration catalyzed by Lewis acids. The migration was found to be reversible and dependent on the electronic effect of substituent R3 of MOBs.
