Yoo, Woo-Jin; Capdevila, Montse Guiteras; Du, Xiangwei; Kobayashi, Shu published the artcile< Base-Mediated Carboxylation of Unprotected Indole Derivatives with Carbon Dioxide>, Computed Properties of 23077-43-2, the main research area is indole carboxylic acid preparation; base carboxylation unprotected indole carbon dioxide.
A simple and straightforward method for the preparation of indole-3-carboxylic acids was discovered through the direct carboxylation of indoles with atm. pressure of carbon dioxide (CO2) under basic conditions. The key for the reaction was found to be the use of a large excess of LiOtBu as a base to suppress the undesired decarboxylation side reaction.
Organic Letters published new progress about Carboxylation. 23077-43-2 belongs to class indole-building-block, and the molecular formula is C9H6FNO2, Computed Properties of 23077-43-2.
