Not only rearrangement but also cyclization occurred in a Fries rearrangement of 1-methoxy-4-(4-methyl-2- and -3-pentenoyloxy)benzenes and gave 5,8-dihydroxy-4,4-dimethyl-3,4-dihydro-1(2H)-naphtalenone.The reduction and oxidation of the dihydronaphtalenone gave 5-hydroxy-8,8-dimethyl-5,6,7,8-tetrahydro-1,4-naphtalenedione and 8,8-dimethyl-7,8-dihydro-1,4,5(6H)-naphtalenetrione, respectively.

(Matrix Presented) The asymmetric synthesis of β-hydroxy-α-amino acids is reported which relies on the use of α,β-unsaturated aryl ester substrates and the dihydroquinyl alkaloid ligand system (DHQ)2-AQN to control the regio- and enantioselectivity of the asymmetric aminohydroxylation (AA) process. α,β-Unsaturated ester substrates of type 1 have a significant effect on the substrate - ligand recognition event which results in a reversal of regioselectivity in the AA reaction.
