- 論文の詳細を見る
The asymmetric Diels–Alder reaction between chiral acrylamides derived from (2R,5R)-2,5-disubstituted pyrrolidines and cyclopentadiene gave (1<I>R</I>,2<I>R</I>,4<I>R</I>)-5-norbornene-2-carboxylic acid amides <B>3a–c</B> with excellent diastereoface selectivity. The amides <B>3a–c</B> were converted into the corresponding carboxylic acid by an iodolactonization-reduction sequence and 2,5-disubstituted pyrrolidines were recovered intact.
