実験手順
A commercially available hydroxy-tetralone or hydroxyindanone is treated with an allyl bromide in the presence of a base such as Cs2CO3 in a solvent such as DMF to afford the ether. Claisen rearrangement in a solvent such as diethylaniline affords the substituted tetralone or indanone. The Mitsunobu reaction then affords the 2-imidazolyl-1-R3-ethoxy)prop-2-enyl compound. Alternatively, the substituted tetralone or indanone is reduced with a catalyst such as RhCl(PPh3)3 in the presence of H2 neat to afford a (prop-2-enyl)phenol derivative. Mitsunobu reaction of the phenol the desired imidazole alcohol affords the 2-imidazolyl-1-R3-ethoxy prop-2-enyl tetralone or indanone derivative.
