“…The first is a deficiency of vegetables and fruit in the contemporary diet, and the second is the potential contamination of this food. In this case, fruit and vegetables do not nourish the human body but become a source of toxins for it, such as heavy metals [6,7], pesticide residues [8], or nitrates [9,10]. For this reason, it is essential to monitor the quantity and quality of vegetables and fruit used for human consumption.…”

Vegetables grown in areas affected by industrial emissions may be subject to contamination with heavy metals. In the present study, this issue was investigated in sweet pepper grown using two different methods and at various distances from a steel mill. Four sites, designated Ko, Po, Wa, and Ru, located at distances of 3.5, 6, 11, and 18 km from a steel mill, were selected for the study. The contents of zinc, copper, nickel, manganese, cadmium, chromium, and lead were determined in the pepper fruits and in the soil. Peppers grown in the vicinity of a steel mill had acceptable contents of all the elements analysed; only cadmium concentrations were excessive for food plants. The study confirmed the effect of a plastic greenhouse on the concentrations of metals in the analysed pepper fruits, whereas the cultivation method had no statistically significant effect on the levels of the elements in the soil. The distance factor also affected the concentrations of metals in the peppers and soil, but to a lesser extent than the cultivation method. The combined effect of both factors was the least pronounced, for all elements in the fruits and in the soil.

Synthesis of 4-Oxoisoxazoline N-Oxides via Pd-Catalyzed Cyclization of Propargylic Alcohols with tert-Butyl Nitrite

et al. 2019

A cyclization of propargylic alcohols with tertbutyl nitrite at room temperature in air was achieved using Pd(OAc) 2 as catalyst. The first reported 4-oxoisoxazoline Noxides could be directly accessed from a range of multisubstituted propargylic alcohols in moderate to excellent yields under mild conditions. Density functional theory calculations indicated that the reaction proceeds through a palladiumcatalyzed NO 2 addition that efficiently generates a ketoxime radical, which eventually produces 4-oxoisoxazoline N-oxide.N itrogenous organic molecules play a crucial role in enriching the carbon-based natural world and are prevalent in compounds investigated in the pharmaceutical industry, 1 the agriculture industry, 2 organic synthesis, 3 and biological research. 4 Moreover, aza-heterocyclic compounds, a class of representative nitrogenous compounds, have drawn extensive attention for their potential biological and pharmaceutical activities. 5 In particular, isoxazoline N-oxides exhibit unique reactivity for the particular structure in this family and are well-known to be versatile building blocks in chemical synthesis. 6 There are several methods for synthesizing isoxazoline Noxides on the basis of relevant literature. In general, isoxazoline N-oxides can be prepared from functionalized aliphatic nitro compounds via intramolecular O-alkylation. 7 However, no general strategy can be used to afford the functionalized nitro precursors. Thus, intermolecular connection synthesis strategies have been developed, and there are two main types: (1) formal [3 + 2] cascade approaches 8 and (2) formal [4 + 1] annulation approaches. 9 In addition, it is reported that βhydroxy ketoximes can be candidates to generate isoxazoline N-oxides, which undergo an intramolecular N−O coupling process by some additive oxidants. 10 In this regard, although
