Ov. Petrova et al., SYNTHESIS OF 1H-2-PYRIDYLPYRROLES AND 1-VINYL-2-PYRIDYLPYRROLES BY THE TROFIMOV REACTION, Mendeleev communications, (4), 1997, pp. 162-163
A one-pot synthesis of 2-(2-pyridyl)-1H-pyrrole and 1-vinyl-2-(3-pyrid
yl)-, 1-vinyl-2-(4-pyridyl)-and 1-vinyl-2-(4-pyridyl)-pyrroles from ox
imes of 2-acetyl-, 3-acetyl- and 4-acetylpyridine and acetylene under
pressure (16-25 arm) in a KOH/DMSO system has been carried out (105-12
0 degrees C, 3 h) to reveal for the first time the applicability of th
e Trofimov reaction for the preparation of alkaloids of the nicotine s
eries.
