A tandem carbonylation/cyclization radical process of 1-(2-iodoethyl)indoles and pyrrole
摘要:
The AIBN-induced radical reaction of 1-(2-iodoethyl)indoles and pyrroles with Bu3SnH under 80 atm of CO was examined. Carbon monoxide was efficiently trapped by an alkyl radical to form an acyl radical which underwent intramolecular addition to the aromatic system to produce bicyclic aromatic ketones after in situ oxidation.

The present invention relates to pharmaceutical compositions comprising an inhibitor of epithelial sodium channel activity in combination with at least one ABC Transporter modulator compound of Formula A, Formula B, Formula C, or Formula D. The invention also relates to pharmaceutical formulations thereof, and to methods of using such compositions in the treatment of CFTR mediated diseases, particularly cystic fibrosis using the pharmaceutical combination compositions.
one equivalent of 2,4,6‐trichloro‐1,3,5‐triazine (cyanuric chloride) generates an easy handling formylatingagent for the efficient formylation of these classes of compounds to give the corresponding aldehydes under mild reaction conditions. This procedure was highly efficient, and a range of formylated indoles and pyrroles were obtained in good to excellent yields.

Annulation of benzoxy‐tethered N‐sulfonyl‐1,2,3‐triazoles and indoles has been developed in this paper, providing an efficient and convenient access to valuable cyclopenta[b]indoles in moderate to good yields. α,β‐Unsaturated imine, which generated in situ from denitrogenation and 1,2‐OBz migration of triazole, provided three carbons for the formal [3+2] cyclization reaction for the first time.
