Saifuddin, Mohammad published the artcileWater-accelerated cationic π-(7-endo) cyclization: application to indole-based Peri-annulated polyheterocycles, Quality Control of 39856-58-1, the publication is European Journal of Organic Chemistry (2010), 5108-5117, S5108/1-S5108/27, database is CAplus.
An efficient and versatile method for the synthesis of indole-based polycyclic indolo-benzazepine and its derivatives e. g., I, II through water-accelerated cationic π-cyclization is described. The strategy involves condensation of arylamine moieties linked to C-4 in indole/azaindole systems with arylaldehydes in water containing catalytic amount of Bronsted acids. The C-C bond formation in water is complete within 10-30 min, furnishing the title compounds in excellent yields and purities, whereas in organic solvents 10-12 h are required. Furthermore, aldehydes both with electron-donating and-withdrawing substituents facilitate the π-cyclization equally.
