    • Because DMT-MM is quantitatively prepared just by mixing CDMT with NMM in THF, addition of 1.1 equiv of DMT-MM and NMM is equal to combination of 1.1 equiv of CDMT and 2.2 equiv of NMM.

    • 3-Thr-OBn. Because of the presence of inseparable impurity, three sets of doublets were observed from this mixture. Calculation of the de value using the most and the second largest peaks afforded 96.0% de, which apparently guaranteed the minimum level of diastereoselectivity.
