Name: 2-MethoxybenzaldehydeIn 2021 ,《Three-Component Efficient Synthesis of 2-Amino-3-cyano-4H-pyrans Catalyzed by Diammonium Hydrogen Phosphate in Aqueous Media》 appeared in Current Organocatalysis. The author of the article were Taghva, Pardis H.; Kabirifard, Hassan. The article conveys some information:
A series of 2-amino-3-cyano-4H-pyrans I [R = 4-MeC6H4, 2-ClC6H4, 3,4-(MeO)2C6H3, etc.] was synthesized by one-pot three-component condensation reactions of aromatic aldehydes RCHO, malononitrile and Me acetoacetate using diammonium hydrogen phosphate (DAHP) in aqueous ethanol at room temperature in excellent yields. All obtained structures were confirmed by their m.ps., IR, 1H NMR, 1C NMR spectroscopy, and also elemental analyses for new derivatives The present method is straightforward, quick, and most efficient green protocol for the synthesis of 2-amino-3-cyano-4H-pyrans using highly inexpensive, easy to handle and nontoxic DAHP as an efficient catalyst in aqueous ethanol medium at room temperature The results came from multiple reactions, including the reaction of 2-Methoxybenzaldehyde(cas: 135-02-4Name: 2-Methoxybenzaldehyde)
2-Methoxybenzaldehyde(cas: 135-02-4) is found in cassia oil, cinnamon bark, and cinnamon bark oil. It is a clear colorless liquid with a strong aroma. It has been used to examine the acaricidal activity of Periploca sepium oil and its active component against Tyrophagus putrescentiae.Name: 2-Methoxybenzaldehyde
