(R)-(-)-2,2-DIMETHYL-1,3-DIOXOLAN-4-YLMETHYL P-TOLUENESULFONATE Chemical Properties,Usage,Production

Chemical Properties

clear yellow to light brown viscous liquid

Uses

(R)-(-)-2,2-Dimethyl-1,3-dioxolan-4-ylmethyl p-Toluenesulfonate is a chiral building block. It is used to prepare the antifungal agent ketoconazole. It is also used to prepare acyclic Nucleotide Analogs Derived from 8-Azapurines with antiviral activities.

Synthesis

98-59-9

23788-74-1

To a solution of (S)-(+)-2,2-dimethyl-4-(hydroxymethyl)-1,3-dioxolane (19a) (4.0 g, 30.2 mmol) in anhydrous pyridine (50 mL) was added p-toluenesulfonyl chloride (6.18 g, 31.7 mmol) in batches over a period of 10 min under ice bath conditions. The reaction mixture was slowly brought to room temperature and stirred overnight, during which a white precipitate was observed to form. Upon completion of the reaction, the pyridine was removed under reduced pressure and the residue was diluted with ethyl acetate (50 mL) and washed sequentially with cold aqueous 1M HCl solution (2 x 150 mL), saturated NaHCO3 solution (100 mL) and brine (200 mL). The organic layer was dried over anhydrous Na2SO4, filtered and concentrated to give a light yellow oil. The crude product was purified by silica gel column chromatography using a 10-30% ethyl acetate/hexane gradient elution to afford (R)-(-)-3-toluenesulfonyloxy-1,2-propanediol acetone compound (20a) (8.54 g, 99% yield, 99.9% ee) as a colorless viscous oily substance. rf = 0.37 (20% ethyl acetate/hexanes).
