Bi(OTf)(3)-catalysed intramolecular cyclisation of unsaturated acetals
A series of highly functionalized carbocycles was efficiently prepared via the selective cyclisation of unsaturated acetals and ketals in the presence of only 1 mol% of Bi(iii) or Fe(iii) triflates as the catalysts at room temperature, with yields ranging from 60 to 90%. With Bi(OTf)(3) catalysis, α...
