High throughput synthesis of 2,5-substituted indoles using a titanium carbenoid bearing boronate functionality [PDF]

open access: yes, 2008
A titanium benzylidene complex bearing a boronate group converted resin-bound esters into enol ethers. Suzuki cross-coupling with aryl iodides followed by cleavage with acid completed the solid-phase synthesis of 2,5-disubstituted N-Boc-indoles.
