A transition-metal-free indole synthesis using radical coupling of 2-halotoluenes and imines via the later-stage C-N bond construction was reported for the first time. It includes an aminyl radical generation by C-H cleaving addition of 2-halotoluenes to imines via the carbanion radical relay and an intramolecular coupling of aryl halides with aminyl radicals. One standard condition can be used for all halides including F, Cl, Br, and I. No extra oxidant or transition metal is required.

Page/Page column 151; 152, (2016/04/20)
The present disclosure is directed to compounds of formula (Ie) and pharmaceutically acceptable salts thereof, wherein A, B, R1, R2, m, n, X1, X2, X3 and X4 are as defined herein, which are active as inhibitors of S-Nitrosoglutathione reductase (GSNOR). These compounds prevent, inhibit, or suppress the action of GSNOR and are therefore useful in the treatment of GSNOR mediated diseases, disorders, syndromes or conditions such as, e.g., pulmonary hypertension, acute respiratory distress syndrome (ARDS), asthma, bronchospasm, cough, pneumonia, pulmonary fibrosis, interstitial lung diseases, cystic fibrosis and chronic obstructive pulmonary disease (COPD).
