Paragraph 0046-0047; 0050, (2020/07/15)
The invention discloses an indole heterocyclic compound as well as a preparation method and application thereof in prevention and treatment of plant diseases. According to the method, indole is reacted with oxalyl chloride to obtain indole oxalyl chloride, then indole oxalyl chloride is reduced by tributylstannane to obtain indole carbonyl acetaldehyde, and finally indole carbonyl acetaldehyde isreacted with a corresponding amino acid under the catalysis of iodine to obtain a compound. The indole heterocyclic compound provided by the invention shows especially excellent plant virus resistingactivity, can well inhibit the tobacco mosaic virus, and also shows broad-spectrum plant pathogenic bacteria resisting activity.

In this work, we accomplished the first total synthesis of chiral alkaloid pimprinol A and the facile construction of its natural congeners: pimprinine, pimprinethine, pimprinaphine, WS-30581A, WS-30581B, laboradorin 1, uguenenazole, balsoxine, texamine in one-pot from commercially available starting materials including amino acids. Further investigating into the mechanism revealed that this improved transformation was achieved by the integration of iodination, Kornblum oxidation, condensation, decarboxylation, annulation, and oxidation reaction sequence.
