Synthesis of N-acyl sulfamates from fluorosulfonates and potassium trimethylsilyloxyl imidates.
JOURNAL OF ORGANIC CHEMISTRY(2019)
摘要
An efficient and operationally simple method for the synthesis of N-acyl sulfamates from fluorosulfonates and potassium trimethylsilyloxyl imidates as amide precursor is reported. This approach showed broad substrate scope, mild and base-free reaction conditions, short reaction time, and high to excellent yields. Notably, we demonstrated the power of this reaction in the rapid late-stage functionalization of three complex phenol-containing bioactive molecules. Given the prevalence of phenol-containing drugs and building blocks, this method is applicable toward a diversity-oriented drug discovery.
