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

Dialkylation of Indoles with Trichloroacetimidates to Access 3,3-Disubstituted Indolenines
2-Substituted indoles may be directly transformed to 3,3-dialkyl indolenines with trichloroacetimidate electrophiles and the Lewis acid TMSOTf. These reactions provide rapid access to complex indolenines which are present in a variety of complex natural ...
