  • Meglumine: A Novel and Efficient Catalyst for One-Pot, Three-Component Combinatorial Synthesis of Functionalized 2-Amino-4<i>H</i>-pyrans

    An efficient one-pot synthesis of functionalized 2-amino-4H-pyrans by a meglumine-catalyzed three-component reaction has been developed. A broad range of substrates including aromatic and heteroaromatic aldehydes, isatin derivatives, and acenaphthenequinone are condensed with enolizable C-H activated compounds and alkylmalonates to give the desired products in high to excellent yields. This methodology provides an alternative approach for rapid access to construct a diversity-oriented library of 4H-pyrans.

    A simple, efficient, one-pot method has been developed for the synthesis of tetrahydro-4H-chromene derivatives by concurrent reaction of aryl aldehydes, active methylene compounds, and 1,3-cyclohexanedins using a catalytic amount of lithium bromide in aqueous media. The present approach offers several advantages such as shorter reaction times, good yields, low cost, recycling of the catalyst, and simple workup.

    for an organic solvent. It is thus enviro-economic with no dangerous wastes produced. The molecular insight on the system shows that magnetized water has a dramatic effect on the strength of the interactions between all organic reagents as well as an increase of a factor of 1.2 in order of the number of hydrogen bonds between water and each organic reagent. In the presence of magnetized water, the reagents
