Abstract

Direct anti-azacarboxylation of 2-alkynylanilines with CO₂ mediated by ZnEt₂ affords indole-3-carboxylic acids efficiently under 1 atm of CO₂. The availability of starting materials and tolerance of various functional groups provide vast opportunities for the efficient construction of diversified libraries for bioactive compounds.
