Reaction Steps

To a stirred solution of (4-hydroxymethyl-cyclopent-2-enyl)-methanol (13.8 g, 107.81 mmol, prepared by method of Mekrami et al., Tetrahedron: Asymmetry 1992, 3, 431) in methylene chloride (100 mL) was added pyridine (25.5 g, 118.59 mmol) and trityl chloride (33.06 g, 118.59 mmol) at room temperature and the mixture was stirred for 18 h. After addition of water (50 mL), the reaction mixture was diluted with methylene chloride (100 mL) and the organic layer was separated. The aqueous layer was further extracted with methylene chloride (100 mL). The combined organic layers were washed with water (100 mL), brine (50 mL), and dried (MgSO4). After filtration, the filtrate was concentrated and the residue was purified on a silica gel column using ethyl acetate in hexanes (0 to 30%), which afforded 18.25 g (45.7%) of desired product, (4-trityloxymethyl-cyclopent-2-enyl)-methanol.
