The authors noticed that the absolute configuration of catalyst 7 employed in the [4+3]-cycloaddition reaction was incorrect. (S,S)-7 should be (R,R)-7 throughout the article. Thus, the following parts should be corrected:
1. Page 263, right column, line 13 from bottom.
2. Page 264, structure in Scheme 1.
3. Page 265, left column, line 6 from bottom.
4. Page 265, structure in Scheme 5.
The correct structure of (R,R)-7 is shown below.

The authors apologize for this mistake and for any inconvenience it may have caused.
