Trimethylsilyl trifluoromethanesulfonate (TMSOTf) reveals, one more time, its enormous
flexibility as Lewis acid catalyst, transforming the well known, but drastic, exchange
of the acetyl group of vinyl acetate with pyrimidine and purine derivatives in a very
gentle and quick method to obtain a whole set of vinyl nucleobases.
