To identify the fate of C1, C2, and C2N in the NosL-catalyzed reaction ofl-tryptophan (10,Fig. 3A), by NMR analysis, various isotopologs ofl-tryptophan were synthesized usingtryptophan synthase. The following procedure was followed:
The Pictet–Spengler cyclization of the imines (3) prepared by the condensation of L-tryptophan methyl ester (1) and aryl methyl ketones (2), using titanium(IV) isopropoxide as an iminating reagent, quantitatively proceeded, when treated with trifluoroacetic acid (TFA) or formic acid, to prov...
The diastereoselective synthesis of optically active 1,3-disubstituted tetrahydro-β-carbolines using polar protic Pictet-Spengler cyclization of (S)-tryptophan methyl ester with five aldehydes RCHO (R═CH(3), C(2)H(5), C(3)H(7), C(4)H(9), and C(6)H(5)) was studied. As an ...
