A reasonable approach to the radical: The establishment of reliable conditions for the radical‐mediated construction of indoles enabled the highly efficient synthesis of tryprostatins A and B. Use of the radical initiator 2,2′‐azobis(4‐methoxy‐2,4‐dimethylvaleronitrile) has allowed to carry out the radical cyclization at just 30 °C, thereby suppressing the formation of by‐products.
