A method for the reductive scission of heterocyclic thioethers
Graham, Thomas H.,Liu, Wensheng,Shen, Dong-Ming
supporting information; experimental part, p. 6232 - 6235 (2012/01/03)
A mild, chemoselective, and generally high-yielding method for the reductive scission of heterocyclic thioethers is described. Suitable heterocycles have a thioether substituent at the 2-position relative to a ring heteroatom. The convenient and straightforward method is demonstrated with reactants which are not compatible with the standard Raney nickel conditions such as sulfides, sulfones, and thiophenes. In addition, benzyl esters, benzyl amides, and benzyl carbamates are tolerated by the reductive reaction conditions.
Suzuki-Miyaura and Negishi approaches to a series of forensically relevant pyridines and pyrimidines
Blachut, Dariusz,Szawkalo, Joanna,Czarnocki, Zbigniew
experimental part, p. 3496 - 3506 (2011/12/04)
A library of 5-aryl-4-methylpyrimidines, phenyl ring-substituted derivatives of 4-benzylpyrimidines, 2,6-benzylpyridines, and 2,6-dibenzyl-4-methylpyridines were prepared. The synthesis of 5-aryl-4-methylpyrimidines was accomplished by Suzuki-Miyaura cross-coupling reaction between arylboronic acids and 5-bromo-4-methylpyrimidine. The 4-benzylpyrimidines and 2,6-benzylpyridines were synthesized by treatment of 4-bromopyrimidine and 2,6-dibromopyridine derivatives with ring-substituted benzylzinc reagents.
