An efficient and convergent one-step synthesis of substituted dihydroquinolin-2-ones from α,β-unsaturated esters and aminoaryl pinacolboronates under rhodium catalysis is reported. The reaction is easily applicable in parallel synthesis format and provide

Crystalline and amorphous forms of methyl 2-(2-oxo-3-indolyl)acetate (1) were obtained showing significant differences in their melting points. The X-ray structure for the trigonal polymorph is reported. In addition, oxindole (1) was easily acid-catalyzed ring enlarged to give the structural isomer quinolone (2) for which the crystal structure was also determined. These results resolve several chemical inquiries related to the structural characterization of 1 and 2.
