Prins fluorination cyclisations: Preparation of 4-fluoro-pyran and -piperidine heterocycles
The Prins reaction was investigated using BF(3)·OEt(2) as a Lewis acid. It has been recently demonstrated, that if BF(3)·OEt(2) is used in stoichiometric amounts then these reactions generate fluorinated products where the BF(3)·OEt(2) contributes fluoride ion to quench the intermediate carbocations...
