Sentence examples for formation of derivative from inspiring English sources

The formation of derivative (5) is indicated by the presence of (C=N) groups in the IR spectra (Fig. 3b) at ν 1593 and 1614 cm−1, respectively, besides no bands of hydroxyl and cyano groups were observed.

Such changes in ploidy are termed meiosis-like adaptation (Storchova 2014) and can result in the formation of derivative and hybrid cells with diverse genotypes and phenotypes, even from the same parental polyploid strain.

The synthetic routes reported in the literature for the formation of derivatives of 6,7-alkoxyisoquinolines as selective PDE10A inhibitors involved multi-step reactions ranging from 3 to 13 steps [67, 68].

This idea was further reinforced by the observation that trapping of the reaction intermediates with iodine, iodomethane, or carbon dioxide, as opposed to a proton, leads to the formation of derivatives 9– 11 (Scheme  5).

The presence of N H stretching at 3500 cm−1 confirmed the formation of hydrazide derivative.

Cyclization of 5 with ethyl cyanoacetate in ethanol in the presence of ammonium acetate at reflux temperature led to the formation of dihydropyridine derivative 6 (Scheme 1) [22–25].

The exposure of nifedipine to UV light leads to the formation of the derivative nitrophenylpyridine [ 12].

The formation of ester derivative was confirmed by means of IR and mass spectroscopy.

This is achieved by its reaction with certain compound leading to the formation of chromophore/fluorescent derivative which can be quantified (Neelima et al. 2012).

However, in many cases the formation of a derivative of A only constitutes the first step of a reaction sequence which ultimately leads to the degradation of P4 to P1-compounds.

In contrast, reactions of aryl-substituted pinacolboronic esters outperformed the coupling of aryl-substituted alkenylboronic acids (4 d, 4 q– aa); particularly notable is the successful formation of cyclopropyl derivative 4 q from boronic ester 24 d.
