    • In this series the THF and THP are easily distinguished by geminal and vicinal coupling constants, the THF having geminal and both vicinal (syn and anti) couplings around 8–9 Hz, while the THP has an axial hydrogen atom next to the PhS group, typical larger geminal couplings (11 Hz) and characteristic vicinal couplings for both axial and equatorial protons.

    • There are of course many cases of cyclisations showing a similar selectivity in the formation of bicyclic products from cyclic compounds, as in sugar chemistry. The closest case seems to be the rearrangement of the hydroxylactone (a), though no mention is made of the presumably trans stereochemistry of (c).
