6ax. Molecular mechanics calculations indicate that 16 is rigid and that the pseudo equatorial α′ proton that is long-range-coupled to the α proton with J = 1.0 Hz should be vicinally coupled to CHOSi with a small coupling constant (1.5 Hz), as is observed. In the diastereomer of 16, the pseudo equatorial α′ proton would be vicinally coupled to CHOSi with a large coupling constant.
