Abstract: Aim To synthesize naturally occurring (-) methyl 2,2-dimethyl-3-hydroxychromanyl-6-formate. Methods Sharpless’ asymmetric dihydroxylation was employed to construct the 3-hydroxychroman. Results First asymmetric syn- thesis of (-) methyl 2, 2-dimethyl-3-hydroxychromanyl-6-formate (1) was accomplished starting from methyl 4-hydroxy- benzoate (2), and the absolute configuration was established. Conclusion A useful method for constructing chiral 3- hydroxychroman by employing Sharpless' asymmetric dihydroxylation is achieved.
