An improved method for the synthesis of some new dihydropyrimidines from aromatic aldehydes, 1,3‐dicarbonyl compounds, and thiourea with significant enhancement in reaction rates, short reaction time (4–6 h), good to excellent yields (70–93%), and ambient temperature using molecular iodine as catalyst is described. The biological evaluation revealed that the newly synthesized compounds 4a, 4b, 4c,
一种由芳族醛,1,3-二羰基化合物和硫脲合成一些新的二氢嘧啶的改进方法,反应速率大大提高,反应时间短(4–6 h),收率高(70–93%)描述了使用分子碘作为催化剂的环境温度。生物学评估表明,新合成的化合物4a,4b,4c,4d,4e,4f,4g,4h,4i,4j和7a,7b,7c,7d,7e,7f,7g,7h,7i,7j对结核分枝杆菌H 37 RV表现出良好的抗菌活性和中等的分枝杆菌活性。
