N,O-acetals are important structures found in many bioactive natural products, and this unique organic functional group can serve as a useful synthetic precursor to the unstable N-acylimines. In this paper, a convenient route to synthesize N-carbamoyl-N,O-acetals and N-acyl-N,O-acetals from enecarbamates and enamides in the presence of alcs. as the solvents and nucleophile sources under Bronsted acid conditions was reported. This strategy could be used to prepare various N,O-acetals from a range of enecarbamates and enamides with light alcs., and the products are obtained in good yields (52-98%). The experimental process involved the reaction of tert-Butyl carbamate(cas: 4248-19-5Electric Literature of C5H11NO2)
tert-Butyl carbamate(cas: 4248-19-5) 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.Electric Literature of C5H11NO2
