Iron-catalyzed cascade reaction of 2-aminobenzyl alcohols with benzylamines: Synthesis of quinazolines by trapping of ammonia
Gopalaiah, Kovuru,Saini, Anupama,Devi, Alka
, p. 5781 - 5789 (2017/07/22)
A novel approach to construct 2-aryl/heteroaryl quinazolines was developed through an iron-catalyzed cascade reaction of 2-aminobenzyl alcohols with benzylamines under aerobic oxidative conditions. The reaction proceeds via the formation of N-benzylideneb

A photoredox catalytic route to carbamates enabled by visible irradiation (or simply sunlight) has been developed. This process leads to a novel approach to the construction of heterocyclic rings wherein the amide or ester motifs of carbamates were assembled from three isolated components. Large-scale experiments were realized by employing continuous flow techniques, and reuse of photocatalyst demonstrated the green and sustainable aspects of this method.
Synthesis of polysubstituted cyclopenta[b]indoles via relay gold(i)/Bronsted acid catalysis

supporting information, p. 557 - 560 (2015/01/09)
An efficient relay catalytic process involving Au(i)/Bronsted acid to access various polysubstituted cyclopentannulated indoles from easily accessible 1-(2-aminophenyl)prop-2-ynols and readily available 1,3-dicarbonyls has been developed. In an unprecedented event, the intermediate 2-indolylmethyl cations undergo the cation-Ene reaction with various 1,3-dicarbonyls followed by an intramolecular Friedel-Crafts-type reaction generating functionalized cyclopenta[b]indoles.

Synthesis of 1-acyl-3,4-dihydroquinazoline-2(1H)-thiones by cyclization of N-[2-(isothiocyanatomethyl)phenyl] amides generated in situ from N-[2-(azidomethyl)phenyl] amides
Kobayashi, Kazuhiro,Matsumoto, Naoki
, p. 923 - 930 (2014/08/05)
An efficient method for the preparation of 1-acyl-3,4-dihydroquinazoline- 2(1H)-thiones 5 has been developed. The reaction of N-[2-(azidomethyl)phenyl] amides 3, easily prepared by a three-step sequence starting with (2-aminophenyl)methanols, with Ph
Intramolecular [2 + 2] cycloaddition of ketenimines with imines. Synthesis and chemical behaviour of azeto[2,1-b]quinazolines
Alajarin, Mateo,Molina, Pedro,Vidal, Angel,Tovar, Fulgencio
, p. 13449 - 13472 (2007/10/03)
Azeto[2,1-b]quinazolines 5 have been prepared by the novel intramolecular [2 + 2] cycloaddition reaction of ketenimines with imines. The applicability and limitations of the synthetic methodology, and explorations on the reactivity of compounds 5 are discussed.
