A group-assisted-purification (GAP) chem. strategy-based Ugi four-center three-component reaction (Ugi-4C-3CR) was explored. The reaction proceeded well to deliver the cyclic fused pyridinones selectively. Moreover, the reaction conditions were mild and avoided addnl. chromatog. or recrystallization workup. Also, wide variations in substrates, such as anilines and aliphatic amines as well as amino alcs. and amino acid esters were all tolerated and pyridinones are achieved in good to excellent yields. Importantly, ladder-type cyclic fused pyridinones can be further constructed in excellent yield of 91%. This study involved multiple reactions and reactants, such as 2-Methoxyethylamine (cas: 109-85-3Reference of 109-85-3).
2-Methoxyethylamine (cas: 109-85-3) belongs to ethers. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Reference of 109-85-3
