Synthesis of tetrahydrofuro[3,2-c]pyridines via Pictet–Spengler reaction
Beilstein Journal of Organic Chemistry, 2023 A semi-one-pot method for the synthesis of 4-substituted tetrahydrofuro[3,2-c]pyridines by the Pictet–Spengler reaction was developed. The method is based on the condensation of easily accessibly 2-(5-methylfuran-2-yl)ethanamine with commercially ...

Acta Crystallographica Section E Structure Reports Online, 2010 The non-H atoms of the title compound, C(6)H(8)N(2), lie in a common plane (r.m.s. deviation = 0.034 Å). In the crystal, adjacent mol-ecules are linked by inter-molecular N-H⋯N hydrogen bonds into a zigzag chain running along the c axis.

Selective Halogenation of Pyridines Using Designed Phosphine Reagents.
Journal of the American Chemical Society, 2020 Halopyridines are key building blocks for synthesizing pharmaceuticals, agrochemicals, and ligands for metal complexes, but strategies to selectively halogenate pyridine C-H precursors are lacking.
