  Preparation of piperidinylpyridines via selective reduction of bipyridines with nickel-aluminum alloy

  摘要：

  Bipyridines were reduced to piperidinylpyridines in modest yield using nickel-aluminum alloy in potassium hydroxide solution. The reduction was selective, and 3-substituted rings were reduced in preference to 4-substitution in preference to 2-substitution. Thus 2,3-bipyridine gave only 2-(3'-piperidinyl)pyridine, 2,4-bipyridine gave only 2-(4'-piperidinyl)pyridine, and 3,4-bipyridine gave only 4-(3'-piperidinyl)pyridine. The symmetrial 2,2'- and 4,4'-bipyridines also gave the corresponding piperidinylpyridines, but the reduction of 3,3'-bipyridine was too sluggish to be practical. The products were identified using C-13 NMR spectrospy, and the C-13 NMR spectra of the starting bipyridines were also recorded.

  日期：——

  Trimethylstannylpyridines 1 were treated with bromopyridines 2 in the presence of catalytic amount of tetrakis(triphenylphosphine)palladium to give the corresponding bipyridines 3 in moderate to good yields. Nicotelline (6) was similarly synthesized from 2, 4-bis(trimethylstannyl)pyridine (5) and 3-bromo-pyridine (2b).
