  2,4-Diamino-5-benzylpyrimidines as antibacterial agents. 8. The 3,4,5-triethyl isostere of trimethoprim. A study of specificity

  摘要：

  3,4,5-Triethylacetophenone was synthesized in 60% yield by a Friedel-Crafts reaction from 4-ethylacetophenone and converted to 2,4-diamino-5-(3,4,5-triethylbenzyl)pyrimidine (2), a trimethoprim (1) isostere, by standard techniques. This compound is more lipophilic than 1 by three log units (log P, octanol/water). Compound 2 was approximately equipotent with 1 in inhibiting Escherichia coli dihydrofolate reductase (DHFR), 2-fold more potent against P. berghei and N. gonorrhoeae DHFR, and 10 and 25 times better an inhibitor of rat and chicken liver DHFR, respectively. Although the 3,4-dimethoxy analogue 19 was 10-fold less inhibitory to E. coli DHFR than 1, it was 3-4 times more potent on the vertebrate isozymes, whereas the diethyl congener 10 followed 19 in its E. coli DHFR binding but was less active on rat and chicken DHFR. Therefore, a significant portion of the selectivity of 1 for bacterial, as opposed to vertebrate, DHFR, involves the methoxy functions. An analysis of the X-ray data on 1 and 2 complexed with chicken DHFR, coupled with kinetic data, led to the conclusion that the difference in binding energies of the methoxy and ethyl compounds probably involve desolvation factors, as well as direct energies of interaction with protein atoms. Thus, one cannot invoke lipophilicity or shape alone in explaining the relationship in properties of 1 and 2.

  strategy has been established for the synthesis of β‐oxo sulfones via visible light‐induced oxysulfonylation of alkenes with arylazo sulfones with dioxygen in air. The present photoinduced transformation proceeds smoothly at room temperature in the absence of an external photosensitizer, which not only provides a mild and efficient approach to various β‐oxo sulfones, but also opens a different reaction

  Selective carbon–carbon and carbon–heteroatom bond cleavage was achieved in a one reaction system. With this strategy a novel Pd/Cu-catalyzed aerobic oxidative oxosulfonation of olefins with DMSO has been developed. Preliminary mechanistic investigations indicated that CO/O2 assisted the bond cleavage and the leaving groups from the starting materials were trapped by O2 and underwent a hydroxylation

  A new iron(III)-catalyzed synthesis of beta-oxo sulfones is described that employs vinylarenes and readily available dimethyl sulfoxide (DMSO) with hydrazine and oxygen as the oxidant. The reaction tolerates various functional group substituents on the vinylarene substrates to afford beta-oxo sulfones in moderate to good yields. The cleavage and formation of the C-S bond are the key steps of this transformation
