The present work reports dendronized polymer based catalysis in which the dendritic cavity and surface functional groups are the reactive centers due to the formation of dendritic unimol. micelle in aqueous medium. First generation amine functionalized tris(hydroxymethyl)propane initiated polyepichlorohydrin cored dendronized polymer TMP-PECH-Amine-G1 was synthesized and properly characterized with different anal. techniques. High functional group capacity, thermal stability and good water solubility are the eye-catching features of the TMP-PECH-Amine-G1 catalyst. The catalytic activity of TMP-PECH-Amine-G1 was studied by synthesizing 4-aryl-1H-1,2,3-triazoles I (R = H, 3-Cl, 4-N(CH3)2, 3,4-(OMe)2, etc.) by one pot condensation reaction of aromatic aldehydes RCHO, nitromethane and sodium azide. The synthesized catalyst offered high yield of products with low catalyst loading in green reaction media without the presence of any external additives. The catalyst was regenerated for six cycles of reaction without substantial loss in activity. This is the first reported method where homogeneous amine functionalized dendronized polymer was used as an organo catalyst for the synthesis of 4-substituted triazoles I. In the part of experimental materials, we found many familiar compounds, such as 2-Methoxybenzaldehyde(cas: 135-02-4Electric Literature of C8H8O2)
2-Methoxybenzaldehyde(cas: 135-02-4) is used as a flavor agent in foods including nonalcoholic/alcoholic beverages, baked goods, chewing gum, confections, frozen dairy, fruit ices, hard/soft candy, instant coffee, tea, Jams, jellies, and milk products. It also has been used to obtain good enantioselectivities using Cu(OAc)(2)-bis(oxazolines) via hydrogen bonding in asymmetric Henry reaction.Electric Literature of C8H8O2
