Several 5-(4-substituted benzyl)-2,4-diaminoquinazolines were prepared as potentially selective inhibitors of Candida albicans dihydrofolate reductase. These compounds were synthesized by a novel route, which included as a key step the displacement of a fluoro group in 2,6-difluorobenzonitrile by the anions of ethyl or methyl 4-substituted phenylacetates. The resultant diarylacetates were saponified
制备了几种5-(4-取代的苄基)-2,4-二氨基喹唑啉作为白色念珠菌二氢叶酸还原酶的潜在选择性抑制剂。这些化合物是通过新颖的途径合成的,该途径包括作为关键步骤的乙基或甲基4-取代的苯基乙酸酯的阴离子取代2,6-二氟苄腈中的氟基团。将所得的二芳基乙酸酯皂化并脱羧成2-氟-6-(4-取代的苯基)苄腈。用碳酸胍将这些苄腈闭环,得到5-(4-取代的苄基)-2,4-二氨基喹唑啉。
