A modular approach for the construction of β- and γ-lactam fused dihydropyrazinones from the readily available Ugi adducts was described. The sequential construction of rings through base-mediated cycloisomerization followed by acid-mediated cyclization yielded β-lactam fused dihydropyrazinones. However, the Ugi-derived dihydropyrazinones afforded γ-lactam fused dihydropyrazinones under base-mediated cycloisomerization. The regioselectivity in the cycloisomerization reactions was explained on the basis of ring-strain. Substrate scope, limitations and mechanistic investigations through DFT-calculations was explored. In addition to this study using 4,4-Diethoxybutan-1-amine, there are many other studies that have used 4,4-Diethoxybutan-1-amine(cas: 6346-09-4Application of 6346-09-4) was used in this study.
4,4-Diethoxybutan-1-amine(cas: 6346-09-4) belongs to anime. The methylamines occur in small amounts in some plants. Many polyfunctional amines (i.e., those having other functional groups in the molecule) occur as alkaloids in plants—for example, mescaline, 2-(3,4,5-trimethoxyphenyl)ethylamine; the cyclic amines nicotine, atropine, morphine, and cocaine; and the quaternary salt choline, N-(2-hydroxyethyl)trimethylammonium chloride, which is present in nerve synapses and in plant and animal cells.Application of 6346-09-4
