    • Although the C9-stereocenter would be eventually lost through oxidation to the ketone, the (9S)-isomer has been shown to be crucial in the success of the macrocyclization reaction, see ref 6b for further discussion.

    • note
    • Attempts to introduce the C8-epoxide on the C11 benzyl ether of 23 were unsuccessful, as no trace of epoxide was detected using m-CPBA.

    • (a) The selectivity of this TPAP oxidation is believed to originate from the positioning of the C11 equatorial proton into the center of the macrocycle making it inaccessible in the oxidative addition step involving the α-C-H bond to the oxo-metal bond (cf.: Ley, S. V.; Norman, J.; Griffith, W. P.; Marsden, S. P. Synthesis 1994, 639-666). (b) For the selective chromic acid oxidation see: Corey, E. J.; Melvin, L. S. Tetrahedron Lett. 1975, 929-932.
