In 2019,Current Organocatalysis included an article by Mosallanezhad, Asiyeh; Kiyani, Hamzeh. SDS of cas: 100-83-4. The article was titled 《Green Synthesis of 3-Substituted-4-arylmethylideneisoxazol-5(4H)-one Derivatives Catalyzed by Salicylic Acid》. The information in the text is summarized as follows:
The efficient and environmental friendliness procedure for the synthesis of isoxazol-5(4H)-ones was introduced. Salicylic acid was used as an inexpensive, easy to handle and safe catalyst for the synthesis of title compounds 3-Substituted-4-arylmethylideneisoxazol-5(4H)-ones were obtained from readily available aryl/heteroaryl aldehydes and β-keto esters via the cyclocondensation reaction without using thermal, microwave or ultrasound conditions. It must be highlighted that the procedure is operationally mild and simple, and the desired small heterocycles were obtained in good to high yields.3-Hydroxybenzaldehyde(cas: 100-83-4SDS of cas: 100-83-4) was used in this study.
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.SDS of cas: 100-83-4
