In 2019,Journal of the Iranian Chemical Society included an article by Maleki, Ali; Eskandarpour, Vahid. Recommanded Product: 3-Hydroxybenzaldehyde. The article was titled 《Design and development of a new functionalized cellulose-based magnetic nanocomposite: preparation, characterization, and catalytic application in the synthesis of diverse pyrano[2,3-c]pyrazole derivatives》. The information in the text is summarized as follows:
In this work, a facile protocol for the preparation of a new cellulose-based functionalized magnetic nanocomposite catalyst is described. The structure and morphol. of the prepared nanomaterial was characterized by SEM, energy-dispersive X-ray anal., X-ray diffraction patterns, and Fourier transform IR spectroscopy analyses. Then, its catalytic activity was investigated in the synthesis of 2,4-dihydropyrano[2,3-c]pyrazole I (R1 = CN, COOEt; R2 = H, 3-OH, 3-NO2, etc.; R3 = H, Me) and spiro[indoline-3,4′-pyrano[2,3-c] pyrazole derivatives II (R1 = CN, COOEt; R4 = 6-NO2, H, 5-Cl; R5 = H, Bn, Et, etc.) through a one-pot four-component reaction between isatin or aldehydes or acetophenones, ethylacetoacetate, hydrazine hydrate, and malononitrile or ethylcyanoacetate in short reaction times, high yields, and mild conditions. The nanocomposite was simply separated by an external magnet and reused several times without remarkable loss of activity. In the part of experimental materials, we found many familiar compounds, such as 3-Hydroxybenzaldehyde(cas: 100-83-4Recommanded Product: 3-Hydroxybenzaldehyde)
3-Hydroxybenzaldehyde(cas: 100-83-4) can be used as a reactant along with ethyl acetoacetate and thiourea in the synthesis of corresponding dihydropyrimidine-2-thione (monastrol), using Yb(OTf)3 as a catalyst by Biginelli cyclocondensation reaction.Recommanded Product: 3-Hydroxybenzaldehyde
