Diacylamines acid amides

The four component condensation (Ugi reaction) " converts a mixture of substituted amine, isonitrile, aldehyde (or ketone) and carboxylic acid (Scheme 6) to a-acylaminocarboxylic acid amides (pathway a), to diacylamines (pathway b) and to a-aminocarboxylic acid amides (pathway... [Pg.405]

Similar reactions involving polymer amide anions yield the corresponding diacylamine structures along with substituted /3-oxoamides, keto amides (XIII) and (XIV). In this way, the sequence of condensation and transacylation results in the formation of five types of 3-keto acid derivatives (X)—(XIV). [Pg.410]

The rate equation for the alkaline hydrolysis of amides such as urea (Lynn, 1965), anilides (Biechler and Taft, 1957 Bender and Thomas, 1961a Mader, 1965 Schowen and Zuorick, 1966), chloroacetamide (Bruylants and K zdy, 1960) andN,N-diacylamines (Behme and Cordes, 1964), is known to contain both first- and second-order terms in hydroxide. It is highly improbable that the term which is second-order in hydroxide is due to base-catalysis of the addition of hydroxide ion to the carbonyl carbon, because of the low acidity of hydroxide.
