One‐Pot Oxidative Heteroannulations ofN‐Sulfonylanilines with Styrenes for the Construction of 5‐Aminocoumaran Derivatives
摘要:
AbstractAn efficient one‐pot oxidative heteroannulation of N‐sulfonylaniline derivatives with styrene derivatives for the rapid construction of 5‐aminocoumaran derivatives is reported. Copper trifluoromethanesulfonate was found to be an excellent catalyst for the oxidative heteroannulation reactions with low reactive styrenes.
