Pitaya is rich in nutrition and unique in function and contains vegetable albumin, anthocyanins, rich vitamins, and water soluble dietary fiber, which are rare in fruits and vegetables. However, researches mostly focused on pitaya cultivation, biological characteristics, fresh‐keeping, and lacked analyses about chemical composition of pitaya. Therefore, ethanol extraction and GC/MS were used to extract and identify the bioactive components in pulp and pericarp of red pitaya and white pitaya. The extracting results showed that percentages of ethanol extracts from pulp and pericarp of red pitaya were 14.5% and 12%, whereas those of white pitaya were 16% and 12%. The GC/MS results showed that different kinds of bioactive constituents were identified in fresh pericarp and pulp of red pitaya and white pitaya. In the four ethanol extracts, there are rich polysiloxane plant organosilicon with total contents of 10.09%, 24.21%, 25.77%, and 23.25%. Meanwhile, there are many heterocyclic substances, and the content of pericarp is much higher than that of pulp. The four ethanol extracts also contain some other bioactive ingredients, such as esters, hydrocarbons, alcohols, amides, halides, and fatty acids, which can be used as raw materials for biomedicine, advanced cosmetics, and skin care products.

A hitherto unknown synthetic pathway for the synthesis of N‐trimethylsiloxy alkyl imidothioates has been presented. The catalyst‐free route uses a range of aromatic, aliphatic, and heterocyclic thiols in the presence of nitroalkanes and hexamethyldisilazane (HMDS). This unusual method expands upon the knowledge of nitro compounds and demonstrates their importance not only as solvents but also as valuable organic reagents. This reaction proceeds under mild conditions and is characterized by excellent yields and a facile workup.

“…Catalytic hydroelementation of unsaturated compounds is an extremely attractive synthetic method in several fields of modern chemistry . It is also the most straightforward and atom‐efficient approach for the incorporation of heteroatoms into various unsaturated systems, which is with academic and industrial importance as these reactions are used in the production of commodity and agrochemicals and material synthesis and also often encountered in chemical synthesis of complex molecules.…”

A greener catalyst for hydroboration of imines—external electric field modify the reaction mechanism

Usually, an extra catalyst (for example, the transition metal complexes) need to be used in catalyzing hydroboration, which involved the cost, environment, and so forth. Here, a greener and controllable catalyst—external electric field (EEF) was used to study its effect on hydroboration of N‐(4‐methylbenzyl)aniline (PhN═CHPhMe) with pinacolboane (HBPin). The results demonstrated that EEF could affect the barrier heights of both two pathways of this reaction. More significantly, flipping the direction of EEF could modify the reaction mechanism to induce a dominant inverse hydroboration at some field strength. That is to say, oriented EEF is a controlling switch for the anti‐ or Markovnikov hydroboration reaction of imines. This investigation is meaningful for the exploration of greener catalyst for chemistry reaction and guide a new method for the Markovnikov hydroboration addition. © 2019 Wiley Periodicals, Inc.
