Isolation and structure of a new alkaloid: aspidocarpine
TL;DR: In this article, a new alkaloid, aspidocarpine, has been isolated from the root bark of Aspidospermmegalocarpon Muell and has the empirical formula C22H30O3N2 and contains an N-acetyl, one methoxyl group, and one active hydrogen.

Synthesis of 2,6-diaryl-3-(trifluoromethyl)pyridines by regioselective Suzuki–Miyaura reactions of 2,6-dichloro-3-(trifluoromethyl)pyridine
Shahzad Ahmed,Shahzad Ahmed,Muhammad Sharif,Muhammad Sharif,Khurram Shoaib,Khurram Shoaib,Sebastian Reimann,Jamshed Iqbal,Tamás Patonay,Anke Spannenberg,Peter Langer +10 more
TL;DR: The Suzuki-Miyaura reaction of 2,6-dichloro-3-(trifluoromethyl)pyridine with 1 ǫ-equiv of arylboronic acids resulted in site-selective formation of 2-aryl-6-chloro- 3-triflormide-3-polytric polytope (S-Pyridine) as mentioned in this paper.
