- 1,3-Methoxy rearrangement of masked o-benzoquinones: A novel synthesis of p-quinol ethers
-
(Chemical Equation Presented) p-Quinol ethers are valuable synthons in synthetic organic chemistry. MOBs 1a-1l 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 fou

- Some Rearrangements of 2,4,6-Tri-t-butyl-4-nitrocyclohexa-2,5-dienone
-
Rearrangement of 2,4,6-tri-t-butyl-4-nitrocyclohexa-2,5-dienone (20) in benzene gives the 4-hydroxy dienone (21) and the mono-de-t-butylated 1,2-benzoquinone (22).The rearrangement is not affected by the addition of mesitylene, but the phenol-coupling product (26) is formed in the presence of p-cresol, and the nitromethyl phenol (31) is formed when the nitro dienone (20) rearranges in the presence of 2,4,6-trimethylphenol (29).The rearrangements of the nitro dienone (20) in methanol are described.
