    • An observation of molecular models reveals that the corresponding trans ring fusion, resulting from attack of water on the α-face of 21, would be a highly strained molecule and, thus, less likely to form.

    • note
    • In part, the difficulty in oxidizing of 30 is due to the poor solubility of this molecule in organic solvents. Advantage was taken in the model system (Scheme 7) of the more desirable solubility properties that these molecules possess prior to diketopiperazine formation.
