Participants

Reaction Steps

A solution of (±)-1-(1,3-dioxolanyl)-2-(1-hydroxy)hexyl-4,5-dimethoxybenzene (Compound 32, 2.2 g, 7.09 mmol), imidazole (0.97 g, 14.19 mmol) and t-butylchlorodiphenylsilane (2.8 mL, 10.64 mmol) in DMF (14 mL) was stirred at 23° C. for 72, hours. The reaction was diluted with Et2O and washed with 1N HCl, H2O and brine. The organic portion was dried (MgSO4), filtered and concentrated in vacuo. Flash column chromatography (silica gel, 5:1 hex/EtOAc) gave 3.52 g (99%) of the title compound wherein absence of the acetal blocking group to give the free aldehyde function was unexpected.
