Trimethylsilyl Trifluoromethanesulfonate Promoted Dipolar Cycloaddition of Nitrones and Silyl Enol Ethers: an Efficient Route to 5-Siloxyisoxazolidines
Dhavale, Dilip D.,Trombini, Claudio
, p. 1268 - 1270 (1992)
The reaction of silyl enol ethers and nitrones, in the presence of trimethylsilyl trifluoromethanesulfonate, gives 5-siloxyisoxazolidines in excellent yield under fairly mild conditions.
