Synthesis of 1H-inden-1-ol derivatives via rhodium-catalyzed annulation of o-acylphenylboronic acids with alkynes
A rhodium-catalyzed annulation reaction of o-formylphenylboronic acid with alkynes occurred regioselectively at room temperature to give substituted 1H-inden-1-ol derivatives. o-Acetylphenylboronic acid also underwent the annulation reaction at 80 degrees C to afford 1-methyl-1H-inden-1-ols.
