Synthesis of novel azonia[5]helicenes containing terminal thiophene rings
Sato,Yamagishi,Arai
, p. 1009 - 1014 (2000)
The Knoevenagel condensation of the 9-methyl derivatives of thieno[3,2-a]- and thieno[2,3-a]-quinolizinium salts (2b and 3b) with appropriate arylaldehydes yielded 9-(arylvinyl)thieno[3,2-a]- and 9-(arylvinyl)thieno[2,3-a]quinolizinium salts (4a-c and 5a-
N-bridgehead heterocyclic compounds thenoyl-substituted. I indolizines and benzoindolizines
Georgescu, Emilian I.,Georgescu, Florentina,Roibu, Constantin,Draghici, Constantin C.,Caproiu, Miron T.
, p. 357 - 362 (2007/10/03)
New thenoyl-substituted indolizine and benzoindolizine derivatives were obtained by the reactions of pyridines and benzopyridines with ω-bromo-2-acethyl thiophene followed by the reactions of corresponding quaternary salts with activated acetylenic compou
A Synthetic Approach toward the Synthesis of Indolizines via 1,3-Dipolar Cycloaddition Reactions of Cycloimmonium Ylide
Tewari, Ram S.,Bajpai, Anita
, p. 505 - 507 (2007/10/02)
Dehydrohalogenation of N-(2-aroylmethyl)-2-picolinium and -4-picolinium bromide, prepared by the quaternization of corresponding bromide salt with triethylamine, afforded a highly reactive cycloimmonium ylide.Its 1,3-dipolar cycloaddition reactions with v
