Diels-Alder construction of regiodifferentiated meta-amino phenols and derivatives

Weaver, Marisa G.,Bai, Wen-Ju,Jackson, Stephen K.,Pettus, Thomas R. R.

, p. 1294 - 1297 (2014/04/03)

Synthetic access to regiodifferentiated meta-amino phenols is described. The strategy relies upon distinct deprotonation conditions to afford regioisomeric thermodynamic and kinetic dienes that undergo a tandem Diels-Alder and retro-Diels-Alder sequence with assorted acetylenic dienophiles to afford a range of aromatic products.
