catalyst-induced one-step synthesis of substituted dihydroquinolines through a hydroarylation/hydroamination cascade reaction undersolvent-freeconditions. A sol-gel method was utilized to prepare the ASM catalyst using tetraethyl orthosilicate (TEOS) and aluminum nitrate (Al(NO3)3.9H2O). The catalytic protocol, utilizing simple starting materials and a heterogeneouscatalyst in a clean reaction environment

A facile and efficient approach toward the synthesis of functionalized quinolines and 1,2‐dihydroquinolines from carbonylcompounds and 2‐vinylanilines is described. The protocol utilizes the nonhazardous and less expensive FeCl3 as catalyst with wide functional group tolerance and avoiding heavy metal impurities in the products.

yields to the 2,2-disubstituted 1,2-dihydro-4-phenyl-quinolines 1–18 (Scheme 1, Table). The structure of the new racemic 1,2-dihydroquinolines 1–18 is determined by NMR spectroscopy. A reaction mechanism proceeding via a 6π-electrocyclic rearrangement of 2-(1-phenylvinyl)anils 19 as the key step is proposed for the formation of these compounds (Scheme 1). The scope and limitations of the novel methods are

AbstractThe catalytic properties of samples of amorphous mesoporous aluminosilicate ASM with different Si/Al molar ratios (40, 80, 160) were studied in the synthesis of practically important pyridines (by the interaction of С2–С5 alcohols with formaldehyde and ammonia, cyclocondensation of acetaldehyde and propionic aldehyde with ammonia), dialkylquinolines and alkyltetrahydroquinolines (by reaction
