Despite major recent advances in C-H activation, discrimination between two similar, unactivated C-H positions is beyond the scope of current chemocatalytic methods. Here we demonstrate that integration of regioselective halogenase enzymes with Pd-catalysed cross-coupling chemistry, in one-pot reactions, successfully addresses this problem for the indole(More)
three complementary biocatalytic routes were examined for the synthesis of the cyclopropyl amine (1R,2S)-2, which is a key building block for the anti-thrombotic agent ticagrelor 1. By employing either a ketoreductase, amidase or lipase biocatalyst, the key building blocks for synthesis of the amine 2 were obtained in 99.9, 92.5 and 46.3 ee, respectively.
