Ethylamine, derivative

In the case of tertiary N-ethylamine derivatives the N-ethyl group is first selectively oxidized by p-chloranil to an enamino group which then condenses with excess p-chloranil to a blue aminovinylquinone derivative [7]. Secondary N-ethyl derivatives do not yield blue aminovinylquinone derivatives they probably react directly with chloranil by nucleophihc attack at one of the four chlorine atoms to yield aminoquinones of other colors [7], It has also been suggested that some classes of substances react to yield charge transfer complexes [1, 5, 8, 12],...

Figure 5. Inhibition of anti-lacto-N-tetraose (R31) by oligosaccharides. Inhibition assays are performed as described in the legend to Figure 2. Abbreviations of oligosaccharides are given in Table I. An abbreviation followed by -OH or etNH, refers to the reduced form or the f3-(p-aminophenyl) ethylamine derivative of the oligosaccharide, respectively.

A chemical relationship similar to that between the trypta-minelike hallucinogens and serotonin exists between the phenyl-ethylamine derivative mescaline and the neurohormone norepinephrine. (Schultes and Hofmann 1973, pp. 17-20)...

An enantioselective synthesis of amino acids has been examined using chiral nonracemic a-imino esters (36) derived from (S)-l-phenylethylamine and (-)-l-cyclohexylethylamine (equation 9, Table 9). Allyl-magnesium, -copper and -titanium reagents react at both the imine and ester carbon atoms of (36), a result of the molecule s ambient electrophilicity. The addition of allyl-, methallyl- and prenyl-9-BBN and -ZnBr to a-imino ester (36), however, generates amines (38) and (39). While the absolute stereochemistry of (38) and (39 R = Ph) has been determined (entries 1-4, Table 9), that of the cyclohexyl-ethylamine-derived products has not (entries 5-8, Table 9). 

Several enantiopure guanidines were studied as the catalysts for the Henry reaction of dibenzylamino aldehydes with nitromethane. (R)-l-(l-Naphthyl)ethylamine-derived guanidine catalysed the reactions of L-isoleucine-derived aldehydes with good diastereos-electivity [42].
