Xanthate-Mediated Incorporation of Quaternary Centers into Heteroarenes

The xanthate-mediated addition of tertiary alkyl radicals to heteroarenes enabled the easy functionalization of heteroaromatic rings as well as more decorated structures, such as marketed drugs or agrochemicals. This work provides a synthetic tool for efficiently exploring the chemical space by allowing late-stage diversification with a high tolerance toward functional groups.

Reaction of 2-Dimethylaminomethylene-1,3-diones with Dinucleophiles. VIII. Synthesis of Ethyl and Methyl 2,4-Disubstituted 5-Pyrimidinecarboxylates

Reaction of ethyl or methyl 2-dimethylaminomethylene-3-oxoalkanoates with N-C-N dinucleophiles such as guanidine, acetamidine or benzamidine afforded in high yields the relative esters of 4-substituted 2-amino-, 2-methyl- or 2-phenyl-5-pyrimidinecarboxylic acids, respectively.These esters were hydrolyzed to the corresponding carboxylic acids, which were converted by heating to 4-substituted 2-pyrimidinamines, 2-methyl or 2-phenylpyrimidines, respectively, generally in excellent yields.The 4-unsubstituted ethyl 2-amino-, 2-methyl- and 2-phenyl-5-pyrimidinecarboxylateswere obtained in moderate yields by reaction of the above dinucleophiles with ethyl 2,2-diformylacetate.These esters were hydrolyzed and the corresponding acids (with the exception of the 2-methyl derivative) were decarboxylated to give 2-pyrimidinamine and 2-phenylpyrimidine in satisfactory yields.

The Chichibabin amination of 4-phenyl- and 4-tert-butyl-pyrimidine

During a study on the amination of 4-phenylpyrimidine in potassium amide/liquid ammonia it was found that the extent to which the SN(ANRORC) mechanism operates in the amination largely depends upon whether an ammonium salt is used in quenching the reaction.The composition of the ?-adduct mixture, the structure of the open-chain intermediates, the inhibition of the SN(ANRORC) mechanism and the course of the amination in apolar solvents have been investigated.In addition, it has been found that, in the amination of 4-tert-butylpyrimidine, the SN(ANRORC) mechanism occurs to only a very limited extent.
