Asymmetric one-pot synthesis of cyclopropanes

Macedonian Journal of Chemistry and Chemical Engineering, 2016
Cycloaddition of the diazoalkanes to electron-deficient olefins (in situ) affords polysubstituted cyclopropanes in high yields (up to 85%). Deprotection of the ketal protecting group provided water-soluble cyclopropane-bearing carbohydrate in good yields.
