Studies of intramolecular Diels–Alder reactions of nitroalkenes for the stereocontrolled synthesis of trans-decalin ring systems

✍ David R. Williams; J. Cullen Klein; Nicholas S.C. Chow 📂 Article 📅 2011 🏛 Elsevier Science 🌐 French ⚖ 830 KB

Studies of thermal IMDA cyclizations of (1E,7E)-1-nitro-deca-1,7,9-trienes and (1E,3Z,7E)-1-nitro-deca-1,3,7,9-tetraenes have been examined. Reactions of these nitroalkenes proceed via transition states featuring characteristics of asymmetric stretch asynchronicity and result in stereoselective form

Intramolecular diels-alder reactions of 2-alkenyl-1,2-dihydropyridines. An approach to the synthesis of the cis-decahydroquinoline ring system.

✍ Daniel L. Comins; Abdul H. Abdullah; Roy K. Smith 📂 Article 📅 1983 🏛 Elsevier Science 🌐 French ⚖ 181 KB

In refluxing decalin P-alkenyl-1-alkoxycarbonyl-1,2\_dihydropyridines undergo an intramolecular Diels-Alder reaction to provide novel polycyclic compounds. The cis-decahydroquinoline ring system can be prepared from the appropriate Diels-Alder product utilizing a ring-opening reverse Mannich reactio
