Method for preparing perindopril despinner and intermediate thereof

The invention discloses a method for preparing perindopril despinner and an intermediate thereof. The method comprises the following steps: halogenating N-propionyl indole-2-carboxylic acid under theaction of a halogenation reagent so as to obtain a halogenation product, and further carrying out amine substitution and catalytic hydrogenation reduction on the obtained halogenation product, therebyobtaining the perindopril despinner. Compared with the prior art, the method is cheap and easy in reaction raw material, has a total yield as high as 64%, is high in product purity and is applicableto industrial production.

Sulfamic acid as a green, reusable catalyst for stepwise, tandem & one-pot solvent-free synthesis of pyrazole derivatives

Sulfamic acid (SA) is a bi-functional, cost-effective and reusable green catalyst for the synthesis of 4-(pyrazol-4-yl)methylenepyrazol-5(4H)-one derivatives by one-pot, three-component condensation of pyrazol-4-carbaxaldehydes, β-ketoesters and phenyl hydrazine (Route-I). In addition to this method, another simple condensation of pyrazol-4-carbaxaldehydes with pyrazolone in the presence of SA under the solvent-free condition in good yield is reported. The merits of these protocols are mild conditions, non-aqueous workup, high yields, easy availability of the catalyst, no chromatographic separation and inexpensive solid acid catalyst. Furthermore, SA could be recycled and reused for five times without losing its catalytic activity.

A new class of efficient 4-[(nitro substituted-phenyl)-hydrazonomethyl]-1-phenyl-1H-pyrazole-3-carboxylate derived colorimetric chemosensor for selective sensing of fluoride and other biologically important anions

A new class of efficient colorimetric chemosensors derived from 4-[(nitro substituted-phenyl)-hydrazonomethyl]-1-phenyl-1H-pyrazole-3-carboxylate have been synthesized and characterized. The synthesized receptors exhibit instant color change from yellow t
