Syntheses of Hydroxylated Bipyridines, II. - 3,4'-Dihydroxy-2,3'-bipyridine
Dehmlov,Eckehard V.,Schulz,Hans-Joachim
, p. 1123 - 1124 (2007/10/02)
The title compound 1 was obtained by coupling of 2-iodo-3-methoxypyridine (3) and 3-bromo-4-methoxypyridine (4) with Nickel (0) - to yield the dimethyl ether 2 (plus 5 and 6) - and by subsequent ether cleavage. 1 is not identical with the alkaloid described under this structure.
Synthesis and Properties of 2,2'-Bipyridin-3-ols and -3,3'-diols
Siemanowski, Werner,Witzel, Herbert
, p. 1731 - 1739 (2007/10/02)
The synthesis of the 2-furyl ketones 5-7 and 13 and their reaction with ammonium acetate in boiling acetic acid to 3-substituted 2,2'-bipyridines and to 2-(2-pyrimidinyl)-3-pyridinol (14) via a ring-transformation reaction are described.Strong intramolecular hydrogen bonds are responsible for their physical and chemical properties.
