《Visible light-induced green synthesis of 2-amino-4H-chromenes》 was published in Environmental Chemistry Letters in 2020. These research results belong to Chen, Lu; Lin, Chuyuan; Lan, Yongyin; Li, Zhenzhen; Huang, Dandan; Yang, Wei; Li, Yibiao. Name: 2-Methoxybenzaldehyde The article mentions the following:
An efficient and green synthesis of 2-amino-4H-chromenes I [R = 4-MeC6H4, 4-ClC6H4, 3-MeOC6H4, etc.], II [R1 = 3-HOC6H4, 4-HOC6H4, 3-O2NC6H4, 4-O2NC6H4, 4-NCC6H4, 3-MeO-4-HOC6H3] and III [R2 = Ph, 4-FC6H4, 4-BrC6H4, etc.] via a photochem. transformation via a multicomponent reaction of malononitrile, benzaldehydes and naphthols/hydroxycoumarins/hydroxy-methyl-pyrones using 9-mesityl-10 methylacridinium perchlorate (Acr+-Mes ClO4-) as a photocatalyst was reported. This procedure possessed several advantages over other reported methods in that it employs a green and sustainable solvent, gave the desired products in excellent yields and avoids the inconvenient preparation of catalyst. 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 used as a flavor agent in foods including nonalcoholic/alcoholic beverages, baked goods, chewing gum, confections, frozen dairy, fruit ices, hard/soft candy, instant coffee, tea, Jams, jellies, and milk products. It also has been used to obtain good enantioselectivities using Cu(OAc)(2)-bis(oxazolines) via hydrogen bonding in asymmetric Henry reaction.Name: 2-Methoxybenzaldehyde
