One of the important Multi-component reaction (MCRs) is the synthesis of dihydropyrano chromene derivatives by one-pot reaction. In this research, an inexpensive and effective one pot three component procedure with good yields for the synthesis of dihydro pyrano chromenes is reported. In this method, the synthesis of pyrano chromene derivatives was followed by using 4-hydroxycoumarin, malononit...

Magnetic Cellulose/Fe3O4/Co3O4 nanocomposite as a new catalyst was synthesized and characterized by FT-IR, XRD, TGA, SEM, TEM, ICP-AES and VSM techniques. The catalytic activity of this heterogeneous catalyst was studied through one-pot synthesis of 1-((benzo[d]thiazol-2-ylamino)(aryl)-methyl)naphthalen-2-ol derivatives from three component reactions of aromatic aldehydes, 2-aminobenzothiazole,...

[bmim][OTf] can promote regio- and chemo-selective glycosylation reactions at room temperature. Furthermore, the applicability to ambient three-component reactivity-based one-pot glycosylation reactions is demonstrated for the synthesis of several trisaccharides.

A novel series of indole and quinoline tricarboxamides were synthesized using simple and efficient one-pot pseudo-five-component reactions of 2-formylindole or 2-chloro-3-formyl quinolines, isocyanides, amines, and Meldrum’s acid as a CH-acid in CH2Cl2 at room temperature. This conversion has been achieved via the construction of new bonds including two C-C bonds, two ...

An  efficient  three-component  one-pot  synthesis  of 1-amidoalkyl-2-naphthols  from  2-naphthol, aldehydes, and acetamide using nano-SnO2as catalyst is described. The reactions were carried out at 80oC under water-solvent media. The structures of the compounds were characterized by IR, 1HNMR, 13C-NMR,  and  Mass  spectra  and  by  elemental  analysis.  The  advantages  of  the  effective meth...

A catalyst-free one-pot three component methodology for the synthesis of α-aminonitriles under ultrasonic irradiation at room temperature using [Bmim]Br as a neutral reaction medium is described. A broad range of substrates including the aromatic, heteroaromatic and aliphatic aldehydes were condensed with amines (aliphatic and aromatic) and trimethylsilyl cyanide (TMSCN). Using this method, all...
