An Investigation into the Regioselectivity of the Acid Catalysed Claisen Rearrangement of Methyl 4- and 5-Allyloxy-2-hydroxybenzoate and Derivatives
Harwood, Laurence M.
, p. 530 - 532 (1983)
The observed products from the acid catalysed Claisen rearrangement of the methyl esters (1c-g) indicate that, unlike the thermal reaction, regiochemical control is independent of internal hydrogen bonding.
Claisen Rearrangement of meta-Substituted Allyl Phenyl Ethers
Bruce, J. Malcolm,Roshan-Ali, Yusuf
, p. 2677 - 2679 (2007/10/02)
Electron-releasing substituents at the 3-position of allyl phenyl ethers favour Claisen rearangement of the allyl group to the 6-position, whereas electron-acceptors favour migration to the 2-position. 2-Acylhydroquinone 4-allyl ethers yield, predominantly, the 3-allyl isomers, probably because internal hydrogen bonding confers naphthalenoid character on the aryl residue.
