Waldmann, Herbert
, p. 671 - 680 (2007/10/02)
Cylopentadiene, cyclohexadiene and alkyl-substituted butadienes react with N-acryloyl-, N-crotonoyl- and N-(4-nitrocinnamoyl)-(S)-proline benzyl and allyl ester in the presence of Lewis acids to give the cycloadducts in high yields and with stereoselectiv
ON THE ENHANCEMENT OF STEREOSELECTION BY COOPERATION BETWEEN CHIRAL AUXILIARIES. ASYMMETRIC DIELS-ALDER REACTIONS WITH FUMARIC ACID BIS((S)-PROLINE BENZYL ESTER) AMIDE
Waldmann, H.,Draeger, M.
, p. 4227 - 4230 (2007/10/02)
Fumaric acid bis((S)-proline benzyl ester) amide reacts with cyclopentadiene in thermal and Lewis acid catalyzed Diels-Alder reactions to give cycloadducts with high yields and diastereomeric ratios up to 100:1.
