In particular, the non-olefmic proton α to the carbonyl in product 19 (from E-enyne 18), would be in an endo-position and, hence, would be more shielded; this proton appears as a multiplet at δ = 2.42-2.47 ppm. The equivalent non-olefinic proton α to the carbonyl in product 6 (from Z-enyne 7), would be in an exo-position and, hence, would be more deshielded; this proton appears as a multiplet at β = 2.90-2.97 ppm.
