Brønsted Acid-assisted Intramolecular Aminohydroxylation of N-Alkenylsulfonamides under Heavy Metal-free Conditions
摘要:
The intramolecular aminohydroxylation of N-alkenylsulfonamides proceeded under heavy metal-free conditions to give substituted prolinol derivatives in high yields. Oxone activated by catalytic Bronsted acid worked well as an electrophilic oxidant for this reaction.
