Participants

Reaction Steps

By the cyclisation procedure described for the preparation of 2-(4-chlorophenyl)-2-bromomethyl-5-prop-1-yltetrahydrofuran (see Example 1), 4-(hydroxymethyl)-2-(2,4-dichlorophenyl)hept-1-ene (1.5 g), bromine (0.88 g), and pyridine (0.43 g) in dry dichloromethane (30 ml) gave 2-(2,4-dichlorophenyl)-2-bromomethyl-4-prop-1-yltetrahydrofuran (1.9 g, 98%) as a pale yellow oil.
