| Abstract: | The asymmetric cycloaddition reaction between 1(SR)ptolysulfinyl3penten2one( 1) and
cyclopentadiene was performed by the catalysis of Lewis acids 2 . The diastereoselectivity
dependent on the size of aryl substituent involved in the chiral ligands was discussed. The
cycloadduct 3 was achieved in a high yield and a high optical purity. The absolute configuration
of the cycloadduct 3 was confirmed. |
