M. Sola et al., AM1 STUDY OF A SUBSTITUENT TRANSFER BY MEANS OF A DIELS-ALDER AND RETRO-DIELS-ALDER TANDEM REACTION, Perkin transactions. 2, (3), 1995, pp. 605-608
An AM1 study of two convergent Diels-Alder reactions shows that the fo
rmal transfer of a substituent from a dienophile to a diene through a
Diels-Alder-retro-Diels-Alder tandem reaction is thermodynamically and
kinetically feasible irrespective of the electron-donating or -withdr
awing character of the substituent.
