Compounds were prepared with heterocyclic replacements for metabolically unstable esters of benzopyranyl indole-2-carboxylic esters, which showed good in vitro and in vivo cardioprotective efficacies possibly through the opening of mitochondrial ATP-sensitive potassium channel (KATP). Initially, indolin-2-yl-heterocycles were constructed using unprotected indoline-2-carboxylic acid, but the cyclization was proceeded with oxidation of the indoline ring to the indole, which did not react with benzopyranyl epoxide. An N-BOC group was introduced to deplete the electron d. of the indoline ring.
