    • The formation of a medium-sized ring by an annulation in which carbon—carbon bond formation at the β-position of an α,β-unsaturated cyclic ketone precedes carbon—carbon bond formation at the α-position is rare; the formation of a seven-membered ring by annulation of a cycloalkenone in which the above order of bond formation is reversed, as in Scheme 2, has apparently not been reported.

    • In order to define the uses of ‘syn’ and ‘anti’ for hydroxy-epoxides such as 5 and 6, the conformation of 4 as depicted in Scheme 2 has been selected, since this is convenient when considering subsequent cyclisations.
