Regiochemistry in Pd-Catalysed Organotin Reactions with Halopyrimidines
Solberg, Jan,Undheim, Kjell
, p. 62 - 68 (2007/10/02)
Chlorines in activated pyrimidine position is replaced by carbon substituents in Pd-catalysed reactions with organotin compounds.The 4(6)-position is more reactive than the 2-position allowing for regioselective coupling in 2,4(6)-dihalopyrimidines.A bromine substituent is required for coupling in the benzenoid 5-position.In 5-bromo-2,4-dichloropyrimidine the 4-chlorine is replaced before the 5-bromine and the latter before the 2-chloro substituent, all in a regioselective manner.The methodology can be used to introduce functionalized carbon substituents into any pyrimidine position.
