[ 1 ] - N,N-Dimethylbiguanide immobilized on mesoporous and magnetically separable silica: Highly selective and feasible organocatalyst for synthesis of β-nitroalcohols
An organosuperbase (N,N-dimethylbiguanide) immobilized on mesoporous and magnetically separable silica supports, was found for the first time, to act as a highly-stable, scalable and efficient heterogeneous catalyst for the Henry reaction under mild and neutral condition. Several factors such as catalyst amount, solvent and reaction time concerning the reactivity were also discussed. The proced...
[ 2 ] - Cellulose/Fe3O4/Co3O4 Nanocomposite as a Highly Efficient and Reusable Catalyst for the Synthesis of 1-((Benzo[d]thiazol-2-ylamino)(aryl)-methyl)naphthalen-2-ol Derivatives
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,...
[ 3 ] - Synthesis of Furo[2,3-d]pyrimidine-2,4(1H,3H)-diones From Alcohols Using T3P/DMSO
T3P/DMSO is shown to be an effective and mild reagent for the one-pot synthesis of furo[2,3-d]pyrimidine-2,4(1H,3H)-diones from a variety of alcohols. Alcohols are oxidized in situ to aldehydes under mild conditions, which undergo a three-component reaction with N,N'-dimethylbarbituric acid and various isocyanides to afford furo[2,3-d]pyrimidine-2,4(1H,3H)-diones in good yields.
