Potassium dihydrogen Phosphate catalyzed one-pot synthesis of 2,3-Dihydro-2-Phenyl-1H-Naphtho-[1,2-e] [1,3] Oxazine, from 2-naphthol, formalin and aromatic amine was grind by pestle and mortar without any solvent at room temperature for specified period of time. The attractive features of this process are inexpensive, efficient, as well as user friendly. DOI: http://dx.doi.org/10.17807/orbital.v11i3.1396

Abstract Chlorosulfonic acid (ClSO 3 H) used to be a catalyst for the synthesis of 2-aryl-1-arylmethyl-1 H -benzimidazoles which was efficiently simple and convenient. This method afforded short reaction time, easy workup, moderate to excellent isolated yields which make this protocol practical and economically attractive.

Multicomponent reactions (MCRs) have been emerged as an extremely powerful tool in combinatorial chemistry and drug discovery, since it offers sign ificant advantages over conven-tional linear step syntheses, in terms to improve classical organic reactions, promote new reactions and develop straightforward synthetic routes for bioactive heterocycles.

Abstract Polyethylene glycol-400 has been found to be a recyclable and rapid reaction medium for the synthesis of 2-amino-4H-chromenes by the condensation of aromatic aldehyde, malononitrile, and α-naphthol. This method gives remarkable advantages such as simple work up, high yields, and a greener method by avoiding toxic catalyst and hazardous solvents.

A simple, highly efficient and environmentally benign method for the synthesis of 3-styrylchromones from 3-formylchromones and 4-nitrophenylacetic acid/4-nitrotolune in the presence of catalytic amount of basic ionic liquid 1-butyl-3-methylimidazolium hydroxide [(bmim)OH] carried out under the influence of microwave irradiation. This method gives remarkable advantages such as, short reaction times, simple work-up procedure and moderate to good yields. The ionic liquid was successfully reused for four cycles without significant loss of activity.

We have described an efficient synthesis of quino[2,3-b][1,5]benzoxazepine α-aminophosphonate derivatives by the nucleophilic addition oftriethyl phosphite to substituted quino[2,3-b][1,5]benzoxazepines promoted by easily available, inexpensive and mild catalyst KAl(SO 4 ) 2 ·12H 2 0 (alum). The reactions proceed smoothly at room temperature under solvent-free reaction conditions and providing high yield of product in very short reaction time.
