Florio, Saverio,Capriati, Vito,Solimini, Maria Cristina,Troisi, Luigino
, p. 8481 - 8484 (1994)
Benzothiazolylchloromethyllithium 1c and benzothiazolyldichloromethyllithium 1e, easily available by lithiation of 1b and 1d (or 1f) respectively, undergo a different type of self-condensation reaction giving 5 and 7a respectively.The possibility that 1c and 1e behave as halocarbenoids is discussed.
Functionalized orthoesters as powerful building blocks for the efficient preparation of heteroaromatic bicycles
Bastug, Gulluzar,Eviolitte, Christophe,Markó, István E.
supporting information; experimental part, p. 3502 - 3505 (2012/08/08)
By combining substituted anilines with functionalized orthoesters, an efficient and connective methodology for the preparation of benzoxazole, benzothiazole, and benzimidazole derivatives has been established. The versatility of this approach enables the development of new libraries of heterocycles containing multifunctional sites.
Synthesis of ethenylbenzothiazole derivatives
Ohba,Kosaka,Wakabayashi
, p. 3421 - 3426 (2007/10/03)
Ethenylbenzothiazoles were synthesized by the Horner-Emmons reaction of benzothiazolylmethylphosphonate with aldehydes under phase transfer catalytic conditions in 60-71% yields. Not only aromatic but also aliphatic aldehydes gave the desired products und
