Structure determination of hydroxytrypargine: A new tetrahydro-beta-carboline toxin from the venom of the spider Parawixia bistriata
(Wiley-Blackwell, 2005-01-01)
A new, highly active tetrahydro-p-carboline toxin from the spider Parawixia bistriata, the most-common species of social spider occurring in Brazil, was isolated. The new toxin was identified as 1,2,3,4-tetrahydro-6-hydr ...

1-Substituted β-carbolines by a Pictet-Spengler cyclization with thioortho esters and carbon-carbon bond formation via N-sulfonyl iminium ions generated from N,S-sulfonyl acetals
(American Chemical Society, 2005-08)
(Chemical Equation Presented) The reaction of N-tosyltryptamines with thioortho esters, leading to 1-thiosubstituted tetrahydro-β-carbolines under modified Pictet-Spengler conditions, is described. The 1-heterosubstituted ...
