Page 5118. The stereochemistry of C-1 in compound 1 was assigned incorrectly. As pointed out by T. Okino, Hokkaido University, C-1 in compound 1 should be assigned as 1S rather than 1R. Thus, the statement in ref 13 is incorrect. Note that the structure in Chart 1 is not in question; the change to be made is only in the nomenclature of compound 1.
