Paragraph 0051; 0054-0055, (2021/06/26)
The invention relates to a trifluoromethylthio-containing tryptamine derivative I and a preparation method thereof, and application of the trifluoromethylthio-containing tryptamine derivative I in prevention and treatment of plant viruses and pathogenic bacteria. According to the invention, the trifluoromethylthio-containing tryptamine derivative I shows anti-plant virus activity, wherein the inhibition rate of the derivative containing chlorine atoms in the structure on tobacco mosaic virus (TMV) can reach the level equivalent to that of virazole; and the compound also shows certain anti-plant pathogenic bacterium activity, and has relatively good inhibitory activity on physalospora piricola.

A novel visible-light-induced radical tandem trifluoromethylation/cyclization of unactivated alkenes with sodium perfluoroalkanesulfinates (Rf = CF3, C3F7, C4F9, C6F13, C8F17) under air atmosphere has been developed. A range of quinazolinones containing unactivated alkene moiety and sodium perfluoroalkanesulfinates were compatible with this transformation, leading to a variety of perfluoroalkyl-substituted quinazoline alkaloids. Remarkably, the experiment can be carried out without any metal catalyst, strong oxidant, or external photosensitizer.

Heterocycles containing N and O are important structures in pharmaceuticals, agrochemicals and functional molecules. The synthesis of these compounds usually requires complex substrates and harsh reaction conditions. Herein, we introduce a mild and efficient electrochemical oxidative strategy to construct benzoxazines, oxazolines and iminoisobenzofurans without the requirement of a transition-metal catalyst and an external oxidant. In a simple undivided cell, various olefinic amides and thiophenols/diselenides react to generate 69 examples of thiolation and selenylation heterocycles in up to 83% yields. Furthermore, this radical cascade reaction provided a facile method for constructing C-S/C-Se and C-O bonds in one step.
