A diastereotopic Pictet—Spengler reaction was performed to form previously unknown 1- and 1,1-substituted 4-phenyl-β-carbolines based on β-phenyltryptamine, aldehydes of various structure, and isatins. It has been demonstrated that the predominant diastereomers of the prepared β-carbolines have the (R*,R*) configuration. The diasteroselectivity (de) of the… (More)
The problem of the analysis of directions field estimation algorithm is considered. The algorithm of estimation of directions field estimates an angle of anisotropy turn. The formulas of calculating accuracy of turn angle estimation of anisotropy are developed in this article. These formulas are received for algorithm on the basis of Radon transformation.
The Pictet-Spengler reaction involving β-phenyltryptamine was shown to be diastereo-specific with formation primarily of the (1S*,4R*) diastereomer of 4-phenyl-1-(2-thienyl)-2,3,4,9-tetrahydro-1H-β-carboline, a compound with potential GABA-receptor activity.
