Synthesis of 5-substituted 2,3-dihydrobenzofurans in a one-pot oxidation/cyclization reaction

Variously substituted 2,3-dihydrobenzofurans have been synthesized according to a sequential one-pot oxidation/cyclization procedure between para-aminophenol derivatives and an azadiene.

Various 2,3-dihydrobenzofurans have been synthesized according to a one-pot oxidation/condensation reaction between substituted para-aminophenols and 2-methylacrolein dimethylhydrazone.
