16 previously reported the isolation of a compound assigned as ii, which has identical spectroscopic data to 21a. We tentatively suggest, on the basis of NOE and other data, that its structure be more correctly represented as the 9β-alcohol, 21a and not the 9α-epimer, 21b. (Chemical Equation Presented)
