Participants

Reaction Steps

A mixture of 1-[6-(4-Vinyl-phenoxy)-pyridin-3-yl]-pyrrolidine-2,2-dicarboxylic acid diethyl ester (4.8 g, 11.3 mmol), sodium metaperiodate (4.8 g, 22 mmol), osmium tetroxide (10 mg) and 2:1 dioxane-water (189 mL) was stirred for 6 hours at ambient temperature. The mixture was quenched with sodium sulfite, diluted with water and extracted 3× with ethyl acetate. The combined organic phases were dried over sodium sulphate, filtered and concentrated in vacuo affording 1-[6-(4-Formyl-phenoxy)-pyridin-3-yl]-pyrrolidine-2,2-dicarboxylic acid diethyl ester as a colorless syrup (4.6 g).
