Creation of New Promoters for Plant’s Root Growth: Its Application for the Syntheses of Vulcanine and Borreline, and for Combating Desertification at Gobi Desert in Inner Mongolia
摘要:
Various new 2-substituted indole-3-carbaldehydes are prepared. Structurally related alkaloids, vulcanine and borreline, are synthesized as well. Among the compounds, 2-haloindole-3-carbaldehydes are found to be potent promoters of plant's root growth. Its successful preliminary application is reported for making Gobi desert in Inner Mongolia full of plant.

The Hendrickson reagent derived from triflic anhydride and triphenylphosphine oxide exhibited high oxophilicity and induced the intramolecular cyclization of β-arylethylamides perfectly. Thus, a one-pot protocol to access isoquinoline and β-carboline was developed involving cyclization followed by oxidative aromatization. Hendrickson reagent - isoquinoline - β-carboline - β-arylethylamide - manganese(IV)

Vulcanine, a β-carboline alkaloid from Haplophyllum vulcanicum
The isolation of a novel β-carboline alkaloid, vulcanine (1-(2-methyl-1-propenyl)-β-carboline) fromHaplophyllum vulcanicum marks the first occurrence of this skeleton in the genus.
