    • Previously, the conversion of 1 to 8 was conducted by a two step sequence consisting of (i) Dess-Martin periodinane-mediated oxidation to give 7, and (ii) warming 7 in acetic acid to promote the β-elimination of a cumyl alcohol; see ref. 1. The facile one-pot conversion of 1 to 8 features the inherent acidic nature of IBX in DMSO. For the discussion on pKa of IBX, see M.J. Gallen, R. Goumont, T. Clark, F. Terrier, and C.M.

    • The prolongation of reaction time resulted in the attenuation of the diasteroselectivity in the Pictet-Spengler reaction of 34, suggesting that C(3) β-36 is the kinetically favored product.
