Decarboxylation in the synthesis of 4-alkyl-, 4-alkenyl- and 4-acylpyrimidines
Herstad, Gunnar,Benneche, Tore
, p. 219 - 224 (2007/10/03)
Decarboxylation of allylic esters of 4-carboxypyrimidines in toluene at 111°C in the presence of a Pd(0) catalyst, gives a mixture of a 4-alkenylpyrimidine and a pyrimidine unsubstituted in the 4-position. If the decarboxylation is carried out in the presence of benzaldehyde, then benzaldehyde is added to the 4-position. Decarboxylation of 4-carboxypyrimidines in the presence of different electrophiles, results in incorporation of the electrophile into the 4-position together with a pyrimidine unsubstituted in the 4-position. Use of microwave irradiation enhances the rate of the decarboxylations.

Compounds of the formula STR1 (wherein X represents a halogen atom; n is 0, 1 or 2; R1 and R2, which may be the same or different, each represents a hydrogen atom or a carboxyl, esterified carboxyl, amido or mono- or di-C1-4 alkylamido group or a C1-4 alkyl group which may if desired carry a carboxyl or esterified carboxyl group; and R3 represents a C1-32 saturated or unsaturated, straight or branched, cyclic or acyclic aliphatic group or an araliphatic or heterocyclic substituted aliphatic group, a heterocyclic group or an aryl group which groups may if desired carry one or more substituents selected from halogen atoms and oxo, nitro, hydroxy, etherified hydroxy, esterified hydroxy, primary, secondary or tertiary amino, acylamino etherified mercapto or S=O or --SO2 derivatives thereof and esterified phosphonic acid groups) and, where an acidic or basic group is present, physiologically compatible salts thereof have been found to be of use in combating abnormal cell proliferation. The compounds are prepared inter alia by oxidation of the corresponding sulfide, displacement of a leaving atom or group from the 2-position of the pyrimidine by reaction with a sulfinic acid or by ring closure of the pyrimidine ring.
