freshly prepared zno nanoparticles were used as an effective heterogeneous base catalyst for the synthesis of aryloximes. the conversion of arylaldehydes and arylketones into the corresponding oximes (up to quantitative yields) was achieved by simply mixing the liquid reactants and hydroxylamine hydrochloride with zno nanoparticles under solvent-free condition. the procedure was carried out und...

[reaction: see text] The synthesis of free alpha-chiral amines by a one-pot multicomponent procedure from commercially available starting materials is described. This enantioselective reaction involves a catalytic asymmetric addition of dialkylzinc reagents to N-diphenylphosphinoylimines with use of an air-stable precatalyst complex 1. The alpha-chiral amines are prepared with a one-pot procedu...

Asavas and arishtas are produced by fermentation in an earthen pot according to textual procedure. The size and shape of the pot and the quantity of the drug. That can be taken in a pot for fermentation is not mentioned in the literature. The present Study was taken up to determine the quantity of drug that can be fermented in an earthen Pot to obtain best results.Dasamularishta was fermented i...

A novel environment-friendly method to access bioactive oroxin A through a one-pot/two-step process from naturally abundant and inexpensive baicalin is described. The procedure presented here has several advantages including clean, one-pot, synthetic ease, and large-scale feasibility. This work also provides a model strategy for rapid and diverse access to natural molecules sharing the common s...

Manganese dioxide is employed as an in situ oxidant for the one-pot conversion of alcohols into imines. In combination with polymer-supported cyanoborohydride (PSCBH), a one-pot oxidation-imine formation-reduction sequence is reported. This procedure enables alcohols to be converted directly into both secondary and tertiary amines.

A novel, one-pot allylboration-Heck reaction of 2-bromobenzaldehydes has been developed for the general and efficient synthesis of 3-methyleneindan-1-ols. Modification of the one-pot procedure to include chiral Brønsted acid catalyzed allylation has allowed the preparation of these building blocks in high enantioselectivity and excellent yields.

We developed a one-pot, two-stage synthetic route to substituted 4-aminoquinolines involving an imidoylative Sonogashira coupling followed by acid-mediated cyclization. This three-component reaction affords pharmaceutically valuable 4-aminoquinolines in a one-pot procedure from readily available starting materials. The reaction tolerates various substituents on the arene as well as the use of s...

an efficient and direct procedure for the synthesis of benzo[h]-indeno[1,2-b]-quinoline derivatives has been described. the procedure employs a three-component condensation reaction in one-pot using 2h-indene-1, 3-dione, naphthalen-1-amine,and aldehydes in the presence of catalytic amount of l-prolinein aqueous media.
