Synthesis of a novel series of 10-oxa-3-aza-tricyclo[5.2.1.0 1,5]dec-8-en-4-ones through an intramolecular Diels-Alder reaction

Milkiewicz, Karen L.,Neagu, Irina B.,Parks, Daniel J.,Lu, Tianbao

, p. 7341 - 7343 (2003)

The synthesis of a novel series of 10-oxa-3-aza-tricyclo[5.2.1.0 1,5]dec-8-en-4-ones through the use of the intramolecular Diels-Alder reaction is presented. The use of this reaction allows for the synthesis of functionalized polycyclic systems in a stereocontrolled manner.
