22. 4). The volatiles were removed in vacuo and the residue was separated by preparative TLC (EtOAc-hexane, 1:4) to give 4, as a mixture of anti and syn diols.
23. 3). Both AB quartets centered around δ 3.75 but had no overlapping of peaks due to the variation in the chemical shift difference between the pair of doublets in the AB quartets for the two isomers (anti isomer: Δδ = 0.28 ppm, J = 13.3 Hz; syn isomer: Δδ = 0.57 ppm, J = 13.2 Hz).
