Ag(I)-catalyzed sequential C-C and C-O bond formations between phenols and dienes with atom economy.
Mild, efficient, and economical Ag(I)-catalyzed sequential C-C/C-O bond formations between phenols and dienes were developed to afford in good yields a variety of dihydrobenzopyran and dihydrobenzofuran ring systems, which are important motifs in both naturally occurring and biologically active compounds.
