Facile Synthesis of Novel 2-Styrylbenzothiazoles Containing Crown Ether Moieties

Abstract

Novel 2-styrylbenzothiazoles containing crown ether moieties with different combinations of O, S, and N atoms were prepared by condensation of 2-methylbenzothiazole with formyl derivatives of benzocrown ethers in the presence of alkali metal alkoxides or by Wittig reaction. The role of complex formation in these syntheses is discussed.

2-styrylbenzothiazole - crown ethers - condensation - Wittig reaction - complex formation
