Synthesis of Tetrahydroindole Derivatives Using Titanium-Nitrogen Complexes Derived from Molecular Nitrogen
Synthesis of tetrahydroindole derivatives was realized from keto-alkyne using titanium-nitrogen complexes generated from Ti(O<I>i</I>Pr)<SUB>4</SUB>, Li, and TMSCl. In this reaction, the electron-withdrawing group on the alkyne gave a good yield, and keto-alkynes having an aromatic ring on the alkyne also gave tetrahydroindole derivatives in good to moderate yields.
