Quinoxaline derivatives exhibit a wide range of biological activities and electron transport properties. The presence of electron withdrawing quinoxaline ring has been used in π-conjugated structures to fabricate the OLED materials. In the present investigation, vinyl benzaldehyde capped quinoxaline derivatives were synthesized using 6-methyl-2,3difurylquinoxaline with terephthaldicarboxaldehyd...

In the title compound, C(23)H(24)N(4)O(3)·H(2)O, the 1,3-oxazoline ring is nearly planar [maximum deviation = 0.059 (2) Å] and its mean plane is twisted by 30.12 (8)° with respect to the quinoxaline fused-ring system; the benzene ring is nearly coplanar with the quinoxaline fused-ring system [dihedral angle = 2.52 (2)°]. The water mol-ecule of crystallization is hydrogen-bond donor to an N atom...
