Chakravarti, R. N.; Dasgupta, B. published an article in 1958, the title of the article was Ultraviolet absorption spectra of aegelin and its derivatives.Category: amides-buliding-blocks And the article contains the following content:
A study of the spectra of aegelin (I), aegelone (II), dihydroaegelin (III), dihydroaegelone (IV) and of related simpler compounds is presented. Absolute alc. was used as a solvent in all cases except with ω-amino-p-methoxyacetophenone-HSO4 (V) with which H2O was used. Concentrations of 2-5 mg./1000 cc. were used. I shows absorption maximum at 212 (log ε 4.36), 219 (log ε 4.36), and 275 mμ (log ε 4.42). I gives trans-cinnamic acid (VI) on hydrolysis and comparison of the spectra of I, VI, trans-cinnamide, and trans-N-methylcinnamide confirmed the trans configuration of the cinnamoyl grouping in I. Other maximum and log ε values obtained were: II, 280, 4.67; V, 216-19, 4.05; 282, 4.27; III, 220, 4.22; 274, 3.78; IV, 271, 4.30. Values obtained for min. and log ε were: I, 216, 4.32; 236, 3.78; 237, 3.78; II, 2.33, 3.95; V, 217, 4.20; III, 217, 4.20; 239, 3.49; 240, 3.49; IV, 233, 3.46; 235, 3.46. The experimental process involved the reaction of N-(2-Hydroxy-2-(4-methoxyphenyl)ethyl)cinnamamide(cas: 456-12-2).Category: amides-buliding-blocks
N-(2-Hydroxy-2-(4-methoxyphenyl)ethyl)cinnamamide(cas:456-12-2) belongs to amides. Amides are pervasive in nature and technology. Proteins and important plastics like Nylons, Aramid, Twaron, and Kevlar are polymers whose units are connected by amide groups (polyamides); these linkages are easily formed, confer structural rigidity, and resist hydrolysis.
