ields in the manuscript were reported incorrectly for
compound 13 (Scheme 4) and compound 18 (Table 3,
Y
entry 6). Correct yields are 81% and 88%.

Solvent peaks had been removed from the H NMR spectra
reported for compounds 13, 9a, 9b, 9c, 9d, 14, 9f, 9g, 9i, 9j, 9k,
6a, 6b, 6h, 6j, 6k, 6n, 17, 18, and 19. Original FIDs were
located, and the spectra were reprocessed and have been
replaced for the above compounds in the revised Supporting
Information submitted with this correction. The spectra editing
did not affect any of the conclusions of the published paper.
The purities calculated on the basis of the revised spectra are as
follows: 13 (98%), 9a (97%), 9b (99%), 9c (99%), 9d (99%),
14 (98%), 9f (94%), 9g (88%), 9i (99%), 9j (99%), 9k (99%),
6a (98%), 6b (97%), 6h (91%), 6j (99%), 6k (97%), 6n (97%),
17 (97%), 18 (98%), and 19 (95%).
