Diastereotopic pair ring chirality

Now we will choose one of the three pairs of Hs in the cyclohexanone example. The starting molecule is, of course, now chiral, and the two molecules we get when we replace each H by G are now diastereoisomers one has G and OMe anti, the other syn, and the pairs of hydrogens are diastereotopic. The same is true for the other CH2 groups. Furthermore, the methyl groups attached to the ring will be diastereotopic too, and we expect them to appear as two 3H singlets.
