Organocatalytic Asymmetric [2 + 4] Cycloadditions of 3-Vinylindoles with <i>ortho</i>-Quinone Methides
Catalytic asymmetric [2 + 4] cycloadditions of 3-vinylindoles with <i>ortho</i>-quinone methides and their precursors were carried out in the presence of chiral phosphoric acid to afford a series of indole-containing chroman derivatives with structural diversity in overall high yields (u...
