A Regioselective Lithiation of 1-Methoxymethoxyindole at the 2-Position and Its Application for the Synthesis of 2-Substituted Indoles
摘要:
A regioselective lithiation of 1-methoxymethoxyindole at the 2-position was achieved with n-BuLi at 0-degrees-C. Subsequent treatment with electrophiles afforded 2-substituted 1-methoxymethoxyindoles, which were readily converted to 2-substituted indoles.

novel dehydroxylation and site-selective 1,7-disulfonylation reaction of diaryl(1H-indol-2-yl)methanols with sodium sulfinates was described. The protocol provided an efficient strategy for the synthesis of disulfonylated 2-(diarylmethyl)indoles by exploring a range of substrates. The mechanistic studies revealed that silvernitrate served as both a Lewis acid and an oxidant for the sequential 1,7-disulfonylation

2-indolylmethanols with indoles has been established, which efficiently afforded bis(indolyl)methane and 3,3′-bisindole derivatives in high yields and with a broad substrate scope (up to 98% yield, 36 examples). This approach will not only provide an important strategy for the diversified synthesis of bis(indolyl)methane and 3,3′-bisindole derivatives but also serve as a good example for substrate-controlled regioselective
A series of indole-fused scaffolds and derivatives was synthesized via the cyclization reaction of 2-indolylmethanols with azonaphthalene. These reactions were realized under mild reaction conditions through catalyst control, providing structurally diverse indolederivatives with moderate to excellent yields. This protocol also shows good substrate adaptability, especially in six-membered ring products
