Sentence examples for amine component from inspiring English sources

Ammonia is rarely used as the amine component in the Ugi reaction, as it reportedly leads to low yields and extensive by-product formation.

Different alkyl and aryl carboxylic acids were tested under the developed reaction conditions using aniline, the amine component, as a constant (Scheme 1).

SAR studies revealed that the substituents on C6 and C7 positions of quinazoline, the amine component of dithiocarbamate moiety and the linker greatly affected the activity.

The preparation of the amine component was achieved via phthalimide protection strategy which occurred to be more efficient than the traditional nitro group reduction.

Coupling reactions were carried out by mixing the water-dispersible nanoparticles of Boc-protected amino acid and amine component in water using DMTMM and then stirring the mixture under neutral conditions for 12 hours at room temperature (Figure 10).

The results reported in Table 4 also suggested that, when diethyl amine is used as amine component, the reaction is affected by the electronic nature of the substituent on the aromatic ring of the benzoic acid (entry r, entry t Table 4) which probably characterize the reactivity of the reaction intermediates.
