Readily available substituted phenols are used as starting materials in a reaction sequence composed of Pd-catalyzed Suzuki coupling and Ru-catalyzed ring-closing metathesis for the controlled construction of functionalized indene derivatives in excellent yields. This approach is also utilized for the synthesis of substituted indenes selectively deuterated in position 3.
