Aza-Payne rearrangement of α,α-disubstituted-aziridinemethanols
摘要:
The aza-Payne rearrangement of activated N-Ts-alpha,alpha-disubstituted-aziridinemethanols, induced by NaOH in the mixed solvent (BuOH)-Bu-t/H2O/THF (4:5:1) or NaH in a mixed solvent of THF/HMPA (10: 1), as well as some N-Boc-alpha,alpha-disubstituted-aziridinemethanols with the latter reagent/solvent combination, provides the corresponding epoxides in up to 99% yield.
