General description

2,4-Dichloropyrimidine is a human skin sensitizer. It undergoes effective one-pot, regioselective double Suzuki coupling reaction to yield diarylated pyrimidines.

Application

2,4-Dichloropyrimidine was used in the synthesis of medicinally important 4-aryl-5-pyrimidinylimidazoles.

[reaction: see text] Starting from 2,4-dichloropyrimidine, a concise synthetic route to medicinally important 4-aryl-5-pyrimidinylimidazoles is described. Sequential substitution of the 4- and 2-chloro groups using a regioselective Sonogashira coupling, followed by nucleophilic substitution, led to pyrimidinylalkyne derivatives, which were then

An effective one-pot, regioselective double Suzuki coupling of 2,4-dichloropyrimidine has been developed, which enables the quick and efficient synthesis of diarylated pyrimidines. The choice of solvent proved critical to the success of this reaction sequence, with alcoholic solvent mixtures affording

There is a strong impetus to develop nonanimal based methods to predict skin sensitization potency. An approach based on physical organic chemistry, whereby chemicals are classified into reaction mechanistic domains and quantitative models or read-across methods are derived for each

A series of 2-dialkylamino-4-phenylpyrimidines (7) was designed and synthesized as CRF(1) antagonists. SAR studies of this series resulted in the discovery of potent and selective antagonists 7b and 7n bearing a 4-(2,4,6-trisubstituted-phenyl) ring and a bulky 2-(N-bis(cyclopropane)methyl-N-propyl)amino group.

Cheap, readily available, air stable, nontoxic, and environmentally benign iron salts such as Fe(acac)(3) are excellent precatalysts for the cross-coupling of Grignard reagents with alkenyl triflates and acid chlorides. Moreover, it is shown that dichloroarene and -heteroarene derivatives as the
