Photocatalysis enables the cascade reactions of indoles and CBr4 in MeOH through a C(sp2)H functionali- zation/methanolysis sequence. The title reaction provides an efficient access to indole 2- and 3-carboxylates in a single operation (no preinstallation of protecting as well as directing groups was required) with good yields under mild reaction conditions.

Abstract
Photocatalysis enables the cascade reactions of indoles and CBr4 in MeOH through a C(sp2)H functionali- zation/methanolysis sequence. The title reaction provides an efficient access to indole 2- and 3-carboxylates in a single operation (no preinstallation of protecting as well as directing groups was required) with good yields under mild reaction conditions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
