Stereoselective Synthesis of Glycomimetic Amines From Biomass‐Derived Cyrene

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
2,3,4‐Trideoxy‐2‐mannosamines, including the unsubstituted one, are accessible as the only endo diastereoisomers by reductive amination of the green solvent Cyrene, derived from pyrolysis of cellulose containing waste biomass. The products are useful chiral synthetic intermediate to nitrogenated glycomimetics.

Investigating the Reactivity and Selectivity in Nucleophilic Fluorination of Secondary Alkyl Bromides and Mesylates: Assessment of the Effect of Counterion and Bulky Alcohols

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Hydrogen bonding provided by pinacol or 2‐trifluoromethyl‐2‐propanol enhances the selectivity of nucleophilic fluorination of several secondary alkyl bromides or mesylates. Synthesis of secondary alkyl fluorides via nucleophilic substitution faces the problem of high competition with E2 processes. This competition depends on the chemical environment of
