A highly enantioselective and straightforward synthetic procedure to chiral 3-hydroxy-2,3-dihydrobenzofurans has been developed by nickel/bisoxazoline-catalyzed intramolecular asymmetric addition of aryl halides to unactivated ketones, giving 2,3-dihydrobenzofurans with a chiral tertiary alcohol at the C-3 position in good yields and excellent enantioselectivities (up to 92percent yield and 98percent ee). The gram-scale reaction also proceeded smoothly without a loss of yield and enantioselectivity.

Aryl phenacyl ethers have been prepared by the micellar catalysed reaction of phenacyl bromide with equimolar mixture of phenol(s)- triethylamine in 70% methanol(v/v) 30 °C. The ethers have been characterised on the basis of their IR, 1H and s
