UV-light intervened synthesis of imidazo fused quinazoline and its solvatochromism, antioxidant, antifungal and luminescence properties.

The photochemical preparation of benzo[4,5]imidazo[2,1-b]quinazoline was assessed under the illumination of UV wavelength (>360 nm). The compound 3,4-dihydronaphthalen-1(2H)-one 1 with 1H-benzo[d]imidazol-2-amine 2 in the existence of KOH/DMF which lead to the aromatized compound 3. The notable remark of this reaction is that the UV irradiation (312 nm) plays a vital part in the formation of compound, 3 in shorter duration (2 h) which resulted in higher yield of 96%.

Cissus quadrangularis mediated ecofriendly synthesis of copper oxide nanoparticles and its antifungal studies against Aspergillus niger, Aspergillus flavus.

Recently, non-toxic source mediated synthesis of metal and a metal oxide nanoparticle attains more attention due to key applicational responsibilities. This present report stated that the eco-friendly synthesis of copper oxide nanoparticles (CuO NPs) using Cissus quadrangularis (C. quadrangularis) plant extract.
