Clean synthesis of 1,8-dioxo-octahydroxanthene derivatives using NBS as an efficient and almost neutral catalyst in aqueous media
author
Abstract:
An efficient one-pot condensation for the synthesis of 1,8-dioxo-octahydroxanthene is achieved through a condensation of aryl aldehydes and 5,5-dimethyl-1,3-cyclohexandione in the presence of NBS. This method enjoys several advantages such as low cost, simple work up procedure and safe reaction condition. In addition, water was chosen as a green solvent.

Clean and efficient synthesis of isoxazole derivatives in aqueous media.
A series of 5-arylisoxazole derivatives were synthesized via the reaction of 3-(dimethyl-amino)-1-arylprop-2-en-1-ones with hydroxylamine hydrochloride in aqueous media without using any catalyst. This method has the advantages of easier work-up, mild reaction conditions, high yields, and an environmentally benign procedure.

An efficient and direct procedure for the synthesis of benzo[h]-indeno[1,2-b]-quinoline derivatives has been described. The procedure employs a three-component condensation reaction in one-pot using 2H-indene-1, 3-dione, naphthalen-1-amine,and aldehydes in the presence of catalytic amount of L-prolinein aqueous media.
