A one-pot three-component condensation reaction of 3-amino-5-methylisoxazole, aryl aldehyde and 2-naphthol to afford the corresponding 3-amino isoxazolmethylnaphthols in good to excellent yields. The remarkable features of this new procedure are high conversions, clean reaction condition, short reaction time, nonhazardous and environmentally friendly reaction condition, inexpensive and easily commercially availability of the catalyst and simple work-up procedures. 相似文献

A green and efficient procedure for the synthesis of α‐aminophosphonates has been developed in water as a green and nonhazardous solvent, from condensation between aromatic aldehydes, aniline, and triphenyl phosphite at 80°C. This methodology has a number of advantages including clean reaction conditions, easy work‐up, and environmentally friendly. 相似文献

In this study, new derivatives of aminoanthraquinone have been synthesized via one-pot three-component condensation reaction of 1- and 2-amino anthraquinones, triethyl orthoformate and CH-acid compounds without using any solvent or catalyst in mild temperature (50 °C). This simple and efficient method yields the desired products in short reaction time (14–50 min) and good to excellent yields (85–96%). Moreover, chemical structures of synthesized products have been entirely confirmed by FT-IR, 1H and 13CNMR and mass spectroscopy and melting points.

We report a new, one-pot, efficient, four-component condensation of hydrazine hydrate, ethyl acetoacetate, arylaldehydes, and malononitrile in the presence of a reusable weakly basic ionic liquid, 1,8-diazabicyclo[5.4.0]-undec-7-en-8-ium acetate, as catalyst, for synthesis of 6-amino-4-aryl-5-cyano-3-methyl-1,4-dihydropyrano[2,3-c]pyrazole derivatives under solvent-free conditions at room temperature. The method has several advantages, for example good yields, short reaction times, and simple work-up procedure. 相似文献

An efficient one-pot three-component procedure has been developed for the preparation of tetrahydrobenzo[b]pyrans, dihydropyrano[3,2-c]chromenes, and pyrano[2,3-d]pyrimidines using nano-SiO2 as catalyst in H2O at 70 °C. This methodology has a number of advantages such as: use of reusable catalyst, easy access, short reaction times, high yields, easy work up and use of non-toxic and green solvent. 相似文献

A novel one‐pot three‐component condensation reaction of an aldehyde, 2‐aminopyrimidine and 2‐naphthol to afford the corresponding 2‐aminopyrimidinomethylnaphtols in good yields. The remarkable features of this new procedure are high conversions, short reaction time, clean reaction profiles, and environmentally benign and simple work‐up procedures. 相似文献
