A metal-free direct C-H selenation of aniline derivatives via an iodine catalysed C-Se bond formation using diselenides as a selenium source at ambient temperature is described. A variety of aniline derivatives underwent regio-selective C-H selenation with different diselenides to afford the corresponding aryl selenoethers in good to excellent yields.
An expeditious synthetic route to access functionalized pyrrolo[2,1-b]quinazoline scaffolds has been achieved via domino ring opening cyclization (DROC) reactions of donor–acceptor (D–A) cyclopropanes and 2-amino(methyl)aniline derivatives.
