    • note
    • The rapidly growing list of amino acids isolated from various natural sources makes the terms unnatural, unusual, noncoded or nonproteinogenic amino acids, which are most frequently used in the literature, dependent on the success of the specific scientific achievements. For instance, amino acids containing the most xenobiotic element fluorine have been shown to be synthesized by microorganisms (see Ref. 7). Therefore, the time independent term tailor-made, meaning rationally designed/synthesized amino acids with presupposed physical, chemical, 3D-structural, and biological features, in the absence of a better definition, seems to be a more appropriate use for such amino acids.

    • note
    • Considering the significant high diastereoselectivity obtained in these reactions, it was of interest to study the asymmetric version of this methylene dimerization using achiral complex 15 and chiral phase-transfer catalyst. Investigation of this catalytic asymmetric methylene dimerization is currently under study and the results obtained will be reported in due course.
