Über Säureamidacetale, Harnstoffacetale und Lactamacetale

Abstract: Als Saureamidacetale, Harnsto5acetale und Lactamacetale werden Verbindungen bezeichnet, in denen die CO-Gruppe der Carbonsaureamide, Harnstoffe und Lactame durch die C(OR)+ruppe ersetzt ist. Es werden Darstellung und Eigenschaften dieser neuen, ungemein reaktionsfahigen Korperklassen beschrieben. Im Gegensatz zu den ihnen zugrunde liegenden Carbonylverbindungen reagieren sie rnit gr6lDter Leichtigkeit und ohne Mitwirkung eines Katalysators mit allen nucleophilen Agenzien, insbesondere kondensieren sie rnit all… Show more

“…When acetal 2 is used as the substrate, acetal 2 initially generates oxonium intermediate A in the presence of Lewis acid. [11] Alternatively, the carbocation F could also be formed in the presence of Lewis acid. We have theoretically investigated the relative stabilities of intermediates A and F in the gas phase and in solution.…”
