“…Increasing of EO yield under salt stress might be due to different reasons. At high temperatures, the biological structure of the oil glands and their epithelial cells can be collapsed in some sensible plants . Moreover, more destruction can take place in plasma membrane structure at higher temperatures that lead to decrease in permeability of plasma membrane .…”

The effect of different NaCl concentrations (control, 2, 4 and 6 dS/m) and three harvesting times in different seasons including spring (9 April), summer (5 July), and fall (23 September) was evaluated on essential oil (EO) yield, composition, phenolic, flavonoid content, and antioxidant activity of myrtle. Essential oil yield ranged from 0.2% in control and fall to 1.6% in moderate salinity (4 dS/m) and spring season. The main constituents obtained from gas chromatography/mass spectrometry analysis were α-pinene, 1,8-cineole, limonene, linalool, α-terpineol, and linalyl acetate in which α-pinene ranged from 11.70% in moderate and fall to 30.99% in low salinity (2 dS/m) and spring, while 1,8-cineole varied from 7.42% in high salinity (6 dS/m) and summer to 15.45% in low salinity and spring, respectively. Salt stress also resulted in an increase in total phenolic, flavonoid content, and antioxidant activity. The highest antioxidant activity based on DPPH radical scavenging activity, reducing power (FTC) and β-carotene/linoleic acid model systems was found in plants harvested in spring and summer in high stress condition. The lowest IC values obtained in 6 dS/m in spring (375.23 μg/ml) followed by summer (249.41 μg/ml) and fall (618.38 μg/ml). Eight major phenolic and flavonoid compounds were determined in three harvesting times using high performance liquid chromatography analysis. In overall, late harvesting time of myrtle in fall can lead to reduce the most of major EO components, while it can improve the amount of phenolic acids.

NaNO₂/K₂S₂O₈‐mediated Selective Radical Nitration/Nitrosation of Indoles: Efficient Approach to 3‐Nitro‐ and 3‐Nitrosoindoles

A mild and selective radical nitration/ nitrosation of indoles with NaNO 2 using K 2 S 2 O 8 as oxidant is developed. Free (NH)-indoles and Nmethyl indoles furnished 3-nitro-and 3-nitrosoindoles respectively, in good yields. Contrary to existing protocols, pyrrole selectively afforded 3nitropyrrole. Mechanistic studies showed that the reaction proceeded via an initial formation of nitroso/oxime intermediate, which is further oxidized to the corresponding 3-nitroindole depending on the substitution on the indole N-atom. Furthermore, synthetic transformations were carried out on the synthesized products towards accessing other valuable compounds.

Recent Advances in Synthesis of Pyrrolo[3,2‐b]indole and Indolo[3,2‐b]indole Derivatives

During the last 15 years, many teams have developed new accesses to pyrrolo[3,2‐b]indoles, indolo[3,2‐b]indoles, and polycyclic counterparts for finding either new synthetic pathways or their electronic and photochromic properties. In this review, we have listed the new methodologies accessing this type of nuclei published between 2007 and the end of 2021 through novel strategies using metal or non‐metal salts. Significant examples of functionalized compounds illustrate the syntheses. We also present the properties of a selection of these heterocycles and evoke some reaction mechanisms.
